​ This is a Team Project made for the Blockchain course at UBB, Romania.

​ The ERC-20 introduces a standard for Fungible Tokens, in other words, they have a property that makes each Token be exactly the same (in type and value) of another Token. For example, an ERC-20 Token acts just like the ETH, meaning that 1 Token is and will always be equal to all the other Tokens.

This is a Solidity Project with a focus on gambling applications using Blockchain.

• Slot Machine

Slot Machine with three spin wheels, seven symbols and a steady cost of 2 LCC (Lucky Casino Coins) per spin.
There are several winning combinations, each with different corresponding sums. The game is in the main casino.sol contract and uses the random generation function found in the same contract.

• Coin Flip

This game synergizes with the main casino contract. :D As a user you can gamble a sum of money to the coinflip, predicting the outcome. It's either heads or tails with a possibility of 49.5% each, which would give you a profit of 2x. You can also be extremely lucky and the coin lands on its side which will give you 99x profit.

• Roulette

The roulette accepts bets from multiple participants at the same time. The bet types and options are listed in the roulette.sol contract comments. One of the players should use the Spin Wheel function which will generate the next roulette number and all bets will be dealt with accordingly.

• Lottery

  ​ Creating a lottery contract, you become the manager and only you can pick a winner. Players can participate but only if they send at least 1Ether to the prize pool. The winner gets the entire prize pool.

  Players	Manager

  ​ The winner is chosen randomly calling the random function keccak256 and take the modulo from the number of players.

  

  ​ The entire idea is that you can deploy a new lottery contract, people start playing and they get added to the players dynamic array, the managers chooses the winner and then we empty the player list for the next round.
