Iris Sluice is a single-player tank run on an open salt field. Drag on the left side of the screen and the hull drives that way. Drag on the right side to turn the gun, then let go to fire one shell. Each shot spends a shell from a drum, and shells return while you wait. The gun stays quiet when the drum is empty.
Salt ribs stand in the field. A rib stops a shell and stops the hull until the rib cracks.
The wide tank circles you. Others rush in or halt and fire. Clear the quota and bring down every ram. Eight sluices grow harder, with a smaller drum, fewer plates, and more rams.
A glow left on the field mends one plate. When the plates reach zero, that sluice ends and you can play it again.
Iris Sluice is a single-player game with no account and nothing to buy.
