Every placed cell scores a point. Completing a row or column clears it — one line is good, several at once is much better, and clearing on back-to-back placements builds a combo streak that multiplies the points. Empty the whole board for a big all-clear bonus.
Everyone in the world gets the same sequence of pieces each day (the day flips at 00:00 UTC). Your first attempt of the day is ranked on the Daily leaderboard; after that you can practice the same puzzle as often as you like, unranked.
Once per run, after game over, you can watch a short ad to clear four random rows and keep playing. With Premium the continue is instant — no ad. It's the only ad in the game; there are no banners and no forced ads.
Settings → Restore Purchases, signed in with the same Apple Account you purchased with.
The continue is offered once per run, and the button only appears when an ad is actually loaded — with no connection (or no ad available) it hides rather than making you wait. Premium removes the ad requirement entirely.
Settings → Color-blind mode switches to a color-blind-safe palette and adds a distinct shape to every block color, so no information rides on color alone.
Leaderboards need Game Center: sign in via iOS Settings → Game Center, then finish a run. Classic runs submit automatically; daily runs submit only the day's first (ranked) attempt.
Only on your device — see the privacy policy. Deleting the app deletes your scores, history, and any run in progress.
