Key to the Tower of Hanoi

Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules: 

  1. Only one disk can be moved at a time.
  2. Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. a disk can only be moved if it is the uppermost disk on a stack.
  3. No disk may be placed on top of a smaller disk.

The Tower Experiment: blending F2P gaming and tokens in Crazy Defense Heroes and Crazy Kings

A crypto experiment on the future of F2P gaming

At  Animoca Brands we fully and unreservedly  embrace blockchain and play-to-earn as the future of gaming, but a major part of our income still derives from free-to-play (F2P) games, such as Power Rangers: Legacy WarsCrazy Defense Heroes, and Snoopy’s Town Tale. As a result, we spend a lot of time considering the question of how to combine blockchain economics with F2P inflationary game design. We have come up with an experimental method to blend together elements of these two very different systems.

F2P and play-to-earn: different by design

Combining blockchain and F2P gaming is challenging for a couple of reasons.

The first is the obvious one, which is that blockchain games usually require fairly significant payment that is antithetical to F2P.

The second is that F2P games are inflationary by design: increases in player base and activity lead to decreases in the scarcity and value of in-game assets. When a player obtains a reward in a standard F2P game, the value he or she receives is created ex nihilo. For example: you kill ten rats and are rewarded with gold and a level 1 potion that the game generates out of nothing, as needed. Every time someone completes the objective to kill 10 rats, more gold and more potions are automatically added to the game economy — effectively without limit. The value of gold and level 1 potions will therefore decrease over time as these virtual assets become more abundant (less scarce); this is inflation at work.

The inflationary model of F2P gaming is intentional because the generation of assets based on player activity rewards and encourages player engagement, provides a level playing field in which all participants have a fair chance, creates opportunities for monetization, and so on.

Blockchain games, on the other hand, are able to limit this inflation because the supply of game assets can be predefined and controlled. For example, our game  F1® Delta Time uses the  REVV ERC-20 fungible token as currency, which has a limited supply and a disclosed schedule specifying how many tokens can be issued over time.

What all this means is that F2P gaming and blockchain gaming approach virtual economies in fundamentally different ways: F2P games are designed to be inflationary in order to generate revenue at the expense of a game’s virtual assets and their scarcity; whereas blockchain games typically seek to generate value **for **their virtual assets and their scarcity.

Reconciling the twain

One of our goals at Animoca Brands is to bring regular gamers into blockchain games. Until now, the way we have done this is to redesign an existing F2P game and its economy for blockchain.

The best example of this is the Sandbox mobile game franchise for Android and iOS, a series of world and game-creation F2P games with millions of users. We are developing

into a new, bigger and bolder multiplayer blockchain title that boasts a virtual economy based entirely on fungible and non-fungible tokens. Our goal for this new game is to create a player-driven multiverse of experiences and expression for all sorts of people: creators, gamers, artists, collectors, businesspeople, and more. You can check it out at  https://www.sandbox.game/ as well as the  SAND token.The Sandbox for blockchain is, effectively, a new game that was designed almost completely from scratch. Although it is based on its mobile game predecessors in the franchise, its design and development have required years of effort and  considerable investment.

What if we could allow existing F2P games to take advantage of blockchain, serve as an introduction to the world of crypto, and offer players the benefits of decentralized economies? Enter the Tower Experiment.

Saga of the Legend of the Tower Experiment

In the closing decade of the 16th century, the great Italian scientist Galileo Galilei is said to have dropped two different objects simultaneously from the Leaning Tower of Pisa to demonstrate that the rate at which objects fall is independent of their mass. This has become known as the Leaning Tower of Pisa Experiment, sometimes informally shortened to the Tower Experiment.

We’re not talking about that kind of tower or that kind of experiment, but anyone interested in the matter should check out commander David R. Scott  performing the experiment on the Moon about 380 years after Galileo’s observation.

Our tower experiment involves the creation of a system that attempts to maintain balance and equitability in a F2P game while introducing the value of blockchain features, including NFTs, DeFi, and governance. To do this, we are going to use one of our most successful franchises: the Crazy Kings games.

The token and a new game: tower defense reimagined

Crazy Kings (CK) and its sequel  Crazy Defense Heroes (CDH) are among our most venerable and respected mobile games. They are successful tower defense games boasting millions of downloads, solid  financial results and a number of blockchain-friendly features, including the deck building of a collectible card game and an RPG character/equipment system.

We are going to introduce a new fungible crypto token for CK and CDH that will have various utility for the entire Crazy Kings franchise and will pave the way for a new blockchain game. Some highlights of our Tower Experiment:

Governance: owners of the tokens will be able to fully participate in the governance of the Crazy Kings franchise, including submitting proposals for the games’ direction and voting on those proposals; these are important steps in giving players a true and effective voice in the roadmap of the game

Crypto economy: owners of the tokens will be able to trade them, thus buying and selling the right to influence the development of the game franchise, and even participate in distributed finance (DeFi) initiatives such as staking (details to be determined)

NFTs: assets in Crazy Kings and Crazy Defense Heroes are represented by game cards, which have different power, value, and rarity. Players will use the token to purchase collectible NFTs that correspond to in-game items; the NFTs will have certain functionalities in the existing games and in the new game

NFT minting: owners of the token will be able to mint NFTs that correspond to in-game cards. Players will be able to trade the NFTs

Currency: the token will be accepted as currency within a PC based blockchain native game that will be the newest addition to the Crazy Kings franchise

Tournament entry fees: tournaments are special events that will challenge the skill, strategy, and game assets of players

**Tournament prizes: **tokens will be distributed as prizes to the victors of competitive multiplayer tournaments, which is a significant step toward full-fledged play-to-earn mechanics.

Earn the token by playing CK and CDH

If the project sketched above is successful, we may be looking at a viable path for traditional games to embrace blockchain — time will tell. In the short term, we will launch an initiative for players of Crazy Kings and Crazy Defense Heroes to “farm” the new tokens simply by playing those games — and have fun playing them!

More details will be forthcoming soon. For now, if you are not already playing Crazy Kings or Crazy Defense Heroes — what are you waiting for? Familiarize yourself with these sophisticated and polished tower defense games at Crazy Kings (iOS) and  Crazy Defense Heroes (Android and iOS).

Please note that we are not doing a token sale at this time; the only way to obtain the new token is by playing Crazy Kings or Crazy Defense Heroes. So get ready to start farming the new tokens and sign up at  https://www.crazydefenseheroes.com/ to receive updates on this project.

Tower Experiment: the Tower Token (TOWER) now paired with ETH and REVV on Uniswap

The Tower Experiment is an initiative to blend traditional free-to-play gaming with blockchain technology. It aims to enable play-to-earn for our players, and to drive adoption of blockchain through traditional gaming. The minting of TOWER tokens is the first step to kickstart our experiment.

TOWER will have various utility for the existing Crazy Kings franchise and will pave the way for the upcoming blockchain PC game. More background about TOWER and the Tower Experiment is available at this Medium post.

TOWER Allocation

We have completed the mainnet deployment and minting of TOWER ERC-20 tokens, creating a total supply of 10,000,000,000 TOWER tokens. You can view the wallet addresses here on Etherscan:  https://etherscan.io/token/0x1c9922314ed1415c95b9fd453c3818fd41867d0b

30% of TOWER is allocated to the Play-To-Earn pool, which is reserved for rewarding players of the _Crazy Kings _franchise over time; this is the largest single pool allocation.

Play-To-Earn Pool: 3,000,000,000


Marketing Fund Pool: 1,500,000,000


Liquidity Pool: 1,500,000,000


Team & Advisors Pool: 1,500,000,000


Company Reserve Pool: 1,500,000,000


Community Development Fund: 1,000,000,000


TOWER paired with ETH and REVV on Uniswap

Starting today, TOWER is paired with  ETH and  REVV on Uniswap. We have provided US$100,000 worth of each token to each of the liquidity pools (i.e. 100,000,000 TOWER and 69.1634 ETH for the TOWER-ETH pool, and 100,000,000 TOWER and 761,597 REVV for the TOWER-REVV pool). These tokens are supplied from the Liquidity Pool described above.

By pairing TOWER with ETH and REVV, we provide real-world value to your gameplay, because any TOWER that you earn by playing Crazy Kings and Crazy Defense Heroes in the future can be swapped for ETH or REVV.

How to Earn TOWER

There are no plans for a TOWER token private sale at this time.

You will be able to earn TOWER tokens by playing Crazy Kings (iOS) and Crazy Defense Heroes (Android and iOS). More information will be released shortly, so make sure you download the games and learn the basics if you are new to the Crazy Kings franchise!

How and Where to Buy Tower token (TOWER) – An Easy Step by Step Guide

You will have to first buy one of the major cryptocurrencies, usually either Bitcoin (BTC), Ethereum (ETH), Tether (USDT)… We will use Binance here as it is one of the largest crypto exchanges that accept fiat deposits.

Binance is a popular cryptocurrency exchange which was started in China but then moved their headquarters to the crypto-friendly Island of Malta in the EU. Binance is popular for its crypto to crypto exchange services. Binance exploded onto the scene in the mania of 2017 and has since gone on to become the top crypto exchange in the world.

Once you finished the KYC process. You will be asked to add a payment method. Here you can either choose to provide a credit/debit card or use a bank transfer. You will be charged higher fees when using cards but you will also make an instant purchase. While a bank transfer will be cheaper but slower, depending on the country of your residence.

Next step - Transfer your cryptos to an Altcoin Exchange

Since TOWER is an altcoin we need to transfer our coins to an exchange that TOWER can be traded. Below is a list of exchanges that offers to trade TOWER in various market pairs, head to their websites and register for an account.

Once finished you will then need to make a BTC/ETH/USDT deposit to the exchange from Binance depending on the available market pairs. After the deposit is confirmed you may then purchase SHIB from the exchange view.

Exchange: 1inch Exchange

Apart from the exchange(s) above, there are a few popular crypto exchanges where they have decent daily trading volumes and a huge user base. This will ensure you will be able to sell your coins at any time and the fees will usually be lower. It is suggested that you also register on these exchanges since once TOWER gets listed there it will attract a large amount of trading volumes from the users there, that means you will be having some great trading opportunities!

Java: How to Get Keys and Values from a Map


Key-value stores are essential and often used, especially in operations that require fast and frequent lookups. They allow an object - the key - to be mapped to another object, the value. This way, the values can easily be retrieved, by looking up the key.

In Java, the most popular Map implementation is the HashMap class. Aside from key-value mapping, it’s used in code that requires frequest insertions, updates and lookups. The insert and lookup time is a constant O(1).

In this tutorial, we’ll go over how to get the Keys and Values of a map in Java.

How to Sort a HashMap by Key in Java

In this tutorial, we’ll take a look at how to sort a HashMap by key in Java.

Let’s go ahead and create a simple HashMap:

Map<String, Integer> unsortedMap = new HashMap();

unsortedMap.put("John", 21);
unsortedMap.put("Maria", 34);
unsortedMap.put("Mark", 31);
unsortedMap.put("Sydney", 24);


We’ve got Strings as keys, and Integers as values. Most of the time, you’ll encounter Integers or Strings as keys, and custom objects, Strings or Integers as values. We’ll want to sort this HashMap, based on the String keys.

HashMapdon’t guarantee to maintain the order of its elements in any case. The order can change through time, and they most definitely won’t be printed back in the order of insertion:


If you re-run this program, it’ll keep this order, since HashMaps order their elements into bins, based on the hash value of the keys. When printing values from a HashMap, its contents are printed sequentially, so the results will stay the same if we re-run the program multiple times.

What are API Keys? and using API Keys

In this video, we use New York’s MTA Bus Time API in order to find bus stops near a given location and determine when a specific bus arrives at a given stop. This API requires an API Key and in this tutorial, we’ll look at what that means and how to affects your http request. Thank you for watching and happy coding!
