Phuzzles
Send someone a photo and it arrives scrambled, with a short message that stays hidden until they put the picture back together. The message appears the moment the last piece lands.
What is unusual: the recipient needs nothing. A puzzle sent as a link opens in any browser, on any device, with no install and no account — where most send-to-a-friend apps require the friend to install first.
What it does not do: no stranger matchmaking. Images are kept while your account exists and are deleted with it, not on a timer. A Plus subscription belongs to the store it was bought in, not to the account.

Oops All Knights
Chess where each side has a king and eight knights, and nothing else. Every piece jumps, so there are no lines to hold, nothing can be pinned, and no check can be blocked by interposing.
What is unusual: the opening theory you know is worthless — no book covers sixteen knights and two kings. A fork is the whole game, and games turn fast. Closest relative is Jeson Mor, which uses a different board and win condition; we would genuinely like to hear from anyone who knows prior art for this exact setup.
What it does not do: no clock, no ratings, no move list, no PGN export, and no matchmaking with strangers — online play is by room code with someone you know. No accounts and no sign-up.
