Colored pieces sit stacked in columns across a hexagonal grid. Lift the matching-color group from the top and move it to a neighboring column. Get four of the same color in one column and it collapses — the pieces above drop in. If that makes four again, that is a chain. ■ One rule to learn, a lot to think about A piece only lands on a neighboring column that is empty or whose top color matches. Empty columns are the only way to untangle a mixed stack, so spend them carefully. Instead of clearing right away, line the same color up above and below to set off a chain. ■ 200 verified levels Every level was checked by an offline solver for solvability before its move budget was set. Past level 200, verified boards keep coming. The board grows from 7 to 13 to 19 cells, and colors go from three up to six. ■ Obstacles that arrive one at a time · Stone — cannot be moved. It cracks when a collapse happens above or below it. · Ice — a color is trapped inside. One adjacent collapse melts it. · Locked cell — opens after a set number of collapses. ■ Turn the board Pinch to zoom and rotate at the same time. Check the colors hidden behind a column and plan your next move. ■ Help when you are stuck Undo, Break and Shuffle are given on every level. If no legal move remains, the board reshuffles itself. Out of a tool, or short on moves? You can watch a short ad for one more — but only if you tap the button. Nothing plays on its own. ■ No purchases, no account, no internet There are no in-app purchases. No paid items, no season pass, no energy meter. There is no sign-up and no login screen. The game itself is fully offline and runs the same in airplane mode. (Ads keep it free. A full-screen ad appears once every three levels cleared, and never before level 5.)
