A bug, a purchase that did not arrive, or an idea?

How does scoring work?

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. The first Unstoppable, Masterful and Legendary clear of each run pays a bonus on top. Empty the whole board for a big all-clear bonus.

What is the Daily Challenge?

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.

How does “continue” work?

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. Undo works the same way: once per run with an ad, unlimited with Premium. Those are the only ads in the game; there are no banners and no forced ads.

The “Watch Ad to Continue” button sometimes isn't there

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.

I bought Premium — how do I get it back on a new phone?

Settings → Restore Purchases, signed in with the same Apple Account you purchased with. Premium is one non-consumable purchase covering the instant continue, unlimited undo and Zen mode; there is nothing to renew.

What is Zen mode?

A Premium mode: a timed calm session on the same board, with no game over, no score pressure and no leaderboard. Five or ten minutes of just placing blocks.

My scores aren't on the leaderboard

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. Achievement progress is tracked locally even before you sign in, and is submitted once you do.

I can't tell the block colors apart

Turn on Settings → Color-blind mode. It switches to a color-blind-safe palette and gives every block color its own distinct shape, so no information rides on color alone. If you find a screen where color is the only signal, that is a bug and we want to hear about it.

Do I need to be online?

No. Lineburst plays fully offline. A connection is only used for ads, leaderboards, and restoring purchases.

Where is my data stored, and how do I delete it?

Only on your device — see the privacy policy. Deleting the app deletes your scores, run history, and any run in progress along with it.
