Koupelnové piškvorky

My 4-year-old refuses to get out of the tub now because the Xs and Os actually stick to the tiles without sliding off. The foam is sturdy enough that we've played three rounds without a single piece getting waterlogged.

My toddler actually stays in the tub long enough to get cleaned now, because these foam Xs and Os float right at the surface and stick to the tiles when he presses them on. The pieces are thick enough that they don't warp after a few soaks, which I wasn't expecting.

The foam pieces stick perfectly to the tile without slipping, and my kids love racing to get three in a row before the water gets cold. It's surprisingly durable after multiple baths.
