Slide the glazes together, fire them at ten
Drop stacks of glazed hex tiles on the board, watch matching colours hop together tile by tile and fire every ten into Bisque the kiln. 70 levels across seven kilns: padlocks, stones and sealed stacks, then glaze gates, ember vents that fire at six, a potter's wheel that turns the rim, and creeping soot. Plus a Daily Firing, Long Firing for the leaderboard, a shop, trophies and a pottery shelf.
Fire the target number of tiles before the board fills up, across 70 levels in seven kilns. Drag a stack of coloured hex tiles from your tray onto an empty cell (or tap the stack, then the cell): matching colours on top of neighbouring stacks slide together, and ten or more of a colour fires into the kiln, which can set off a chain. Later kilns add glaze gates that only take their own colour on top, ember vents that fire at six, a potter's wheel that turns the rim, and soot that creeps until you fire next to it; Long Firing is the endless leaderboard mode.
