We bet these toys take you back to your childhood.  The toymaker TOMY created a line of Waterful games like ring toss and tic-tac-toe.

The games worked via water pressure.  The button on the right-hand corner sent a jet of air through the water.  The ring or small plastic ball would then be shot into the water.  Can you make the ring land on the hook or ball into the plastic cradle.

Was it cheating to tilt the game to try to manipulate the ring?

The games appear to still be available on Amazon and eBay.
