About Crossover 21

Crossover 21 turns everyday ideas into a small logic challenge. You look at what is on the board, decide what the level is really asking for, and work it out one move at a time. Each level has a clear win state, and the difficulty comes from spotting the trick the puzzle is hiding rather than from twitchy timing. Visuals stay simple on purpose, so the puzzle itself stays in the foreground. Animations are short, and feedback is immediate when a move works. Players who enjoy sudoku, mahjong, or match-3 games will feel at home here. The learning curve is gentle, but later levels do not hold your hand.
