Nuts and Bolts
Sort the nuts so each bolt holds one colour
Slide stacks, match colours, pop ten!
Hexa Stack is a calm sorting puzzle played on a board of hexagon tiles. Drag a little stack of coloured tiles from your tray onto an empty tile. Next to a matching colour, tiles flow across one by one, and ten of a colour pop with a happy chime. Fifty levels bring locked tiles, tricky goals and tight placement limits, plus an endless mode that saves your best score. Every colour has its own shape, so it is easy to play for everyone.
