B4B4 game

B4B4 game is a vertical endless link-matching mobile game that combines pattern pairing with path planning. Players tap two identical patterns and clear them along a straight line or a path with at most two turns through empty spaces, earning one point for each pair cleared. After the board is cleared, the next wave begins, with more pattern types gradually appearing and the board becoming more crowded. Hints can mark a clearable pair, shuffle can rearrange the remaining layout, and undo returns the last pair to its original place; uses are limited, so they should be saved for critical moments. When no legal path can be found on the board, the round ends. The rules are clear at a glance, yet players must keep challenging higher waves through trade-offs and rhythm.
