Tips & strategy
Practical advice for longer runs and higher scores.
Think in sets of three
You always see the full tray. Before placing the easiest piece, scan all three shapes and imagine where each will go. Leaving a awkward 1×4 or T-piece for last without space is the most common way to end a run early.
Protect the center
Holes in the middle of the board are harder to fill than edge gaps. Try to keep the core flat and build outward. A single unreachable cell can block multiple large shapes later.
Rotate before you commit
A quick tap to cycle orientation is free. Long pieces often fit after one rotation when the default orientation looks impossible — especially along board edges.
Hunt star gems
Plan clears that pass through ★ cells for easy +150 bonuses. Even one star per clear adds up over a long streak. Do not cover stars with throwaway placements if a better line is one turn away.
Chain your clears
Set up back-to-back line clears whenever possible. The streak multiplier applies to line-clear points only, but those bonuses dominate late-game score. Sometimes it is worth placing a smaller piece specifically to complete a line and keep the chain alive.
Use swaps wisely
Reordering the tray costs nothing but a drag gesture. Swap the piece that fits a tight corner into the slot you reach for most often. See Mechanics for swap rules.
Save room for big shapes
Keep at least one 2×2 or 3-wide open zone when you can. A 2×2 square or four-long bar appears often and needs uninterrupted space.
When the run is doomed
If two pieces are used and the last shape clearly does not fit anywhere, consider whether a tray refresh (when available) is worth an ad before forcing a game over. Continues work best when you still have checkpoint space with recoverable structure.
