The pieces are decided before you start. Every run is generated from a seed you can read, copy and share. Dealing never looks at your board, your score, whether you are close to a record, or whether you paid. The piece weights are printed inside the game. That is the whole promise, and you can check it. WHAT IS IN IT · 300 levels across 30 named chapters, with four kinds of goal: free the crystals, clear a number of lines, land a double clear in one move, or sweep the board down to almost nothing · When a piece has exactly one spot left that fits, the game points at it — free, always, never behind an ad · Endless mode with combo scoring: the streak is where the points are · A daily puzzle — the same pieces worldwide, so scores really are comparable · A coach built from the same solver that verifies every level is winnable: it shows the best move, and after a loss it tells you which move cost you the run · 500 collectible angel artworks, 20 themes, 44 achievements, daily quests and streak rewards ABOUT ADS No interstitials at all for your first 50 games. After that, at most one every 10 games, and only after a win — never mid-game, never on a loss. Everything else is a rewarded video you choose to watch; decline and nothing happens. Plays offline.
