About this game
No ads. See every piece before you place it.
Quarterfill is a sequence-planning puzzle on an 8×8 board split into four 4×4 quarters. Every campaign level shows its complete fixed piece sequence. Hold three pieces at a time and scroll the strip above the board to see everything still to come.
FOUR QUARTERS, ONE GOAL
A quarter clears when all sixteen squares are full; rows and columns clear too. On marked levels a gold frame surrounds a quarter already part-filled with stones. Fit the matching pieces into its holes, clear the quarter and its stones, then finish the goal.
200 LEVELS, EVERY ONE PROVED
Play 200 campaign levels across four difficulty tiers. Marked quarters start at level 1. Every level is checked by a solver before release. If your placements leave a board that cannot be finished, the game tells you.
ONE FAIR DAILY
Everyone gets the same fixed Daily board with one ranked attempt and no account required. The server replays your placements before ranking the result. Offline play is clearly unranked. From 31 October 2026 the Daily adds two marked quarters; until then it retains the previous Daily rules for fairness across existing versions.
GAUNTLET
Play a chain of proved rounds with a visible sequence in each. Your score carries forward until a round beats you.
PLAY YOUR WAY
Drag pieces above your finger or choose tap-to-place. Adjust left-handed layout, contrast, sound, haptics and motion in Settings. No lives, energy, paid retries or paid ranked advantage.
Free, forever: today's ranked Daily, the first 20 campaign levels, three Gauntlet runs a day, one undo per level and the complete tutorial.
A one-time Quarterfill unlock opens all 200 levels, Gauntlet runs with no daily cap, the complete Daily archive, unlimited non-ranked undo, solver-backed hints and advanced records. Or choose StackForge Play Pass (monthly or annual) — Pro in every StackForge game plus One Good Thing. PlateStack is separate. Prices are shown before you buy. Manage or cancel in Google Play → Payments & subscriptions.
