build a Java FX game

Must Know How to use github and Intellij Your first task is to choose a simple one-player, two-dimensional (2D) board game, and then implement the 'engine' of that game in Java. You should write some unit tests to check that your game logic works correctly. You second task is to use JavaFX to add a graphical user interface (GUI) to your game, which displays the 2D board and allows the user to play the game. So you must keep the basic game idea fairly simple, and ensure that it is not too hard to add the GUI to it. You MUST use JavaFX, not any other Java GUI libraries.
