Hexa Stack Reserve Slot Puzzles
Play Hexa Stack levels 126–150 and 176–200 with a one-use reserve slot that changes the order of your stacks.
Play the first puzzleWhat makes these puzzles different?
The reserve slot holds one selected tray stack and immediately draws a replacement. You can place the held stack later, but can only store once per level.
How to approach them
Before storing, compare the three top colors with the locked branches. Save a stack that can trigger a clear after a gate opens, then use slot 4 when its landing is ready.
Play 50 matching levels
Each level opens its own playable board and a tip based on that puzzle.
