Quoxxo
Binary Logic Puzzle.
$0.49
A well known binary logic puzzle reimagined. No ads, no tracking. A shared challenge for a solitary puzzle.
Quoxxo is a clean, quiet binary logic puzzle. Fill every square in the grid with an X or an O until the whole board obeys three simple rules — then share it, or race a friend on the exact same puzzle.
If you enjoy Binairo, Takuzu or other binary logic puzzles, Quoxxo will make you feel right at home.
THE RULES
- Never three of the same symbol in a row or column
- Each row and each column holds an equal number of X's and O's
- No two rows are identical, and no two columns are identical
Every puzzle has exactly one solution. There's no guessing — just logic.
THREE SIZES, PLUS A DAILY
- Easy — 6×6 grid
- Medium — 8×8 grid
- Hard — 10×10 grid
- A new Daily puzzle every day, the same board for everyone
RACE A FRIEND — NO SERVER NEEDED
Every puzzle has a 7-character code. Send it to a friend and you'll both get the identical grid, so you can see who solves it faster. No account, no login, no server. Just a code.
