About
Classic games, remade for iPhone Duo. The fold becomes part of the game in a way a flat phone never could.
Made for iPhone Duo, and works great on any iPhone and iPad.
Half-folded, the raised screen covers your board like the lid of a game box. The shared board sits upright, while your own side lies flat in front of you.
Fold shut to pass. The outer screen tells the next player it's their turn. When they open it, their side stays covered until they tap Reveal.
On any other iPhone or iPad, a Pass button does what the fold does.
PASS & PLAY
• Broadside: the classic game of hiding and sinking ships.
• Who's Who: ask yes or no questions and find their secret person first.
• Liar's Dice: hide your dice, raise the bid, call their bluff. Two to four players.
• Codebreaker: hide a colour code and crack theirs in fewer guesses. Take turns, or play full rounds.
• Fog of War: chess where you only see what your pieces can reach.
ACROSS THE TABLE
Lay flat between you.
• Chess, with an optional clock.
• Four in a Row.
ON YOUR OWN
Every game has a computer opponent on Easy, Medium or Hard.

What's New in Twofold
1.0.3
October 26, 2026
Prices now come straight from the App Store. If the App Store can't be reached, Twofold shows no price instead of a wrong one. On iPhone Duo: - Opening the phone from shut into book pose shows your Cover, not the Pass screen. A half-fold mid-turn keeps your turn. - Broadside's Cover now hides every ship and shot behind the frost. Also: - Restore Purchases says so plainly when it can't reach the App Store. - A rating prompt can appear after two finished games, and never over the Home sheets. - Crash reports no longer carry free text, and location lookup is switched off.
