Match Masters turns match-three into a duel: two players take turns on the same board, so every move you make also changes what your opponent can do next. A move that scores well for you but leaves them a cascade is a bad move.
Boosters are charged by specific tiles — blue stars charge yours, red circles charge theirs — which adds a second layer of decisions on top of the matching.
You share the board with a live opponent and take turns, so every move sets up their next one. Denying them a good board matters as much as scoring.
Matching blue stars charges yours; matching red circles charges your opponent's — so which tiles you clear is a strategic choice, not just a scoring one.
Yes — you play head to head against another player, with tournaments and global leaderboards.
