Twofold
Pass and play

Classic games for iPhone Duo.

Seven classic games to play on one device. Half-folded on its side like a laptop, the raised screen covers your board, so only you can see your side.

Broadside in Twofold on iPhone: the other fleet's board at the top, your fleet and the Fire button below.

The fold keeps your board hidden.

On iPhone Duo, half-fold the phone on its side and the raised screen hides your board from the other player.
