Prism Cascade: Hex Sort Puzzle

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.
