Playable prototypes.
Next round ready.

Press an exposed hinged shutter to preview how it changes both layer access and the powered route, then release to commit. Power every required terminal at once.

Tap a cell to drop an orb. Fill a cell past its neighbour count and it bursts into every neighbour, flipping them to your colour and setting off cascades. Take every orb on the board to win.

Drag across the board and release to drop a disc. Discs stack from the bottom. Line up four in any direction before the opponent does.
