How to play Binairo Race
Goal. Solve the same grid as your opponent, faster. The first correct grid wins.
The grid
- Both players receive the same 8 × 8 Binairo grid with a single solution. Fill every open square with a seed or a sprout.
- No more than two alike next to each other in a row or column.
- Every row and column holds four seeds and four sprouts.
- No two rows are the same, and no two columns are the same.
The race
- You both play at once, each on your own copy. Your opponent cannot see your squares.
- When your grid is full, press Check. The first correct grid wins the race.
- A wrong check costs time: you must wait 10 seconds before checking again, then 20, then 30.
Controls
- Tap a square to cycle it: seed, sprout, empty. Keyboard: arrow keys move, 1 places a seed, 2 a sprout, 0 or Backspace clears. Red marks show broken rules on your own grid.
Tips
- Two alike side by side force the other plant on both ends; a gap between two alike forces the middle.
- Once a line has four of one plant, the rest of that line is the other plant.
- Check only when every square is filled and no red marks remain: a penalty can decide the race.
