Onchain Game on the Ethereum blockchain:
It supports dynamic grid sizes and includes essential game mechanics such as starting a game, placing mines, and revealing cells. Players can only reveal cells if their game is in progress, and the game ends either when a mine is triggered or all non-mine cells are revealed. Winning or losing a game is reflected by emitting events, and players' game states are updated accordingly. The contract also includes functionality to increase the grid size upon winning and handle game state transitions efficiently. With each Size increase one new mine is beeing added to the board. It starts at 3x3 and 1 Mine, next level: 4x4 and 2 mines and so on
