Peekaboard: confirm a turn, then fold to reveal your fleet
Navid Gooranourimi's naval battle for two in the Duo simulator: the phone lies flat between you, a half of the sea each, and on your turn you fold your half up to see your fleet. A handover screen makes the next player confirm first.
This idea belongs to Navid Gooranourimi. FoldHunt shows the post through X's embed data (or the creator's own player and page) and keeps no copy of their media. Made something for the fold? Send it in.
