Swipe any row left or right to slide its blocks — they wrap around the edges. From level 4, columns slide too.
Tap two touching blocks to swap them. Handy for fixing a stubborn pair — but every swap counts as a move.
MATCH rounds: make every column a single color. MISMATCH rounds: no column may contain the same color twice.
PAR: finish at or under the par move count to earn ×2 points. The counter up top shows moves/par.
