TwofoldTwo-Player Games on One Phone: Seven You Can Play Today
Two players, one phone
Pass the phone between turns. A game that hides something from each player, such as a fleet, a dice roll or a secret person, works on one phone when the screen covers your side as the phone changes hands. A game with nothing hidden works when the phone lies flat between you.
Twofold has seven games for two people on one phone. It is free to download, and each game is free to play once. Download the app and every game is inside it.
How the phone keeps your side secret
Between turns a cover names the next player and hides the board. That player taps Reveal to see their own side. On iPhone Duo, Broadside also uses the fold: half-folded on its side, the raised screen covers your side. How pass-and-play works explains each step.
The seven games
Broadside. Hide your fleet and fire shots to sink theirs before they sink yours. Each player hides a fleet, so it uses the cover.
Who's Who. Each player picks a secret person from the same 24 faces. Take turns asking one yes or no question, flip down the faces that no longer fit, and guess when you know.
Liar's Dice. Roll five dice under a cup, bid on how many dice of a face are on the table, and call liar when you think the bid is too high. It takes two to four players.
Codebreaker. Hide a secret code of coloured pegs and crack the other player's code in fewer guesses. Small pegs show how close each guess came.
Fog of War. Chess where you only see what your pieces can reach. Capture the king to win.
Chess. Play the full game with a board turned to face each player and a clock you can set.
Four in a Row. Drop discs in turn. First to line up four wins.
Which games suit one phone best
Games with hidden information suit one phone, since the cover keeps your side secret: Broadside, Who's Who, Liar's Dice, Codebreaker and Fog of War. Chess and Four in a Row have nothing to hide, so the phone lies flat between two players and by default each player gets half of the screen.
What does it cost?
Twofold is free to download, and each game is free to play once. After that you can buy a game on its own, or all games in one purchase, including games added later. The App Store shows the price in your currency.
Can you play against the computer?
Yes. Every game has a computer opponent, so you can play alone as well. Every game has easy, medium and hard levels. In Codebreaker they also set the code length (4, 5 or 6).
