How to play & accessibility
Exchange tiles between a market and a nine-slot hand. Uniform market rows and mirrored hand pairs must coexist; the middle hand slot is your unpaired buffer. Tap a Hand button, then a market cell to swap their colors. Match all three horizontal market rows and all four mirrored hand pairs, then Audit. Hand slot5 is unpaired. Identical swaps and premature audits are free rejections. Seven exchanges maximum; Undo restores both sides. No tiles are created or destroyed, so use one side to temporarily store the other’s colors.
