Groups of same-coloured blocks clear when tapped, and the pieces above fall into the gap. What lifts it above a simple tapping game is the objective bar: each level asks for specific tiles, in specific quantities.

That turns every tap into a decision. The largest available group is often the wrong one to take if it does not move you toward the target, and levels have limited moves.

Read the objective first, always. Then find clears that produce the tiles you need rather than the ones that look most satisfying. Chain reactions are useful but only when they happen in the right colour.

Genuinely tight on later levels, where the move limit leaves no room for a wasted clear.
