Mosaic Blocks is a 9×9 puzzle. Your tray always holds three polyomino pieces: drag them onto the board or place them with a tap. Fill a row, a column, or a 3×3 square completely and it clears, freeing up space. Place all three tray pieces and a new set arrives. Fair generator: a set is never dealt dead — at least one piece is guaranteed to fit the board when dealt. From there it is your planning: no piece rotation, no timer. Run scores add up into mastery and unlock patterns inspired by Russian folk crafts: Gzhel, Khokhloma, Maiolica, Mezen, Zhostovo, Finift — six palettes, switch between runs from the collection screen. Three rewarded boosters help out: swap the tray, clear one cell with a hammer, or get a move hint. After a loss you get a second chance: the bottom three rows are cleared. An unfinished run is saved until next time. The game is endless: no levels, no timer, no multiplayer and no daily quests — just the board, three pieces, and your best score.
How to play
Drag a piece from the tray onto the board, or use tap-tap: touch a piece, then a board cell — it snaps there. Pieces never rotate, so pick the right spot yourself. Fill a row, a column, or a 3×3 square completely to clear it. Clearing several zones in a row without missing builds a streak bonus. Once the tray is empty, a new set arrives — the generator guarantees at least one of the three pieces fits the board at the moment it's dealt. The run ends when none of the three tray pieces fit anywhere. Watching an ad unlocks: a full tray swap, a hammer (remove one cell), or a move hint — each booster works once per run. After game over you can watch one ad for a "second chance": the bottom three rows clear and the run continues.
