C-Back is a color puzzle built around hidden layers and chain reactions.
Place the next color on the board. Connect four or more tiles of the same color horizontally or vertically to clear their top layers. The colors underneath may form another match, turning one move into a chain reaction.
Inspect the colors hidden in each cell and plan your next move. Keep clearing tiles on consecutive moves to build combos and raise your score. Clear the entire board for an all-clear bonus.
Choose how you play:
• 4×4 or 5×5 boards
• Four or five colors
• Unlimited play or a move limit
• Optional obstacle blocks
An interactive tutorial helps you learn the rules. You can resume a game in progress and track your best scores and play records.
Stack colors, match four tiles, and set off satisfying chain reactions.
