About Stack Sort
A tidy-brain puzzle with a hoarder’s twist. Drag stacks of coloured pieces between slots — colours only land on their own kind, and the instant a pile hits ten it clears with a very satisfying pop. The NEXT queue keeps feeding you new stacks, so lazy placement snowballs into a jammed board fast. The undo button is there, and using it is not weakness, it is board management.
How to Play
Drag a stack onto a matching colour (or any empty slot). A pile of 10 same-coloured pieces clears the slot. Watch the NEXT queue and keep space open — a full board with no moves ends it.
💡 Tips & Strategy
Serve the nearly-full colour first. A pile at 7 or 8 is a clearance you can force in one or two placements — free board space is worth more than any tidy arrangement.
Keep one slot as scratch space and defend it. The failure mode is a board where every slot is a half-committed rainbow; a reserved dump slot keeps one colour flowing while the queue misbehaves.
Play the NEXT queue, not the current piece: if the queue shows three greens coming, stop scattering green. Undo is board management, not shame — one undone mistake is ten forced moves saved.
