Byna Grid: Logic Puzzle

Lush Games Developers

About this game

Can you fill the grid using only logic?

Byna Grid is a clean, satisfying binary logic puzzle. Place 0s and 1s in every cell — but three simple rules stand between you and a perfect grid.

──── THE RULES ────
• No three consecutive identical numbers in any row or column
• Every row and column must have an equal number of 0s and 1s
• No two rows can be identical — no two columns either

Every puzzle has one solution. Find it.

──── 120 HAND-CRAFTED LEVELS ────
Six difficulty tiers take you from gentle 6×6 grids to demanding 12×12 challenges:

◉ Starter — 6×6 Learn the rules, build your instincts
◉ Easy — 6×6 More to think about, still approachable
◉ Medium — 8×8 Tighter constraints, longer chains of logic
◉ Hard — 8×8 Fewer starting cells, more deduction required
◉ Expert — 10×10 Serious puzzles for serious solvers
◉ Master — 12×12 144 cells. Pure logic. No guessing.

──── FEATURES ────
✓ Real-time rule highlighting — violations light up instantly so you learn, not just get penalized
✓ Row & column completion indicators — green dots confirm each line is done correctly
✓ 3 hints per puzzle — reveals one correct cell when you're stuck
✓ Unlimited undo — experiment freely without restarting
✓ Timer — track how fast you solve each puzzle
✓ Star ratings — earn up to 3 stars per level (fewer hints = more stars)

✓ Sound effects — satisfying placement clicks, toggle off anytime
✓ No ads, no internet required, no data collected

──── HOW TO PLAY ────
Tap any empty cell to place a 0. Tap again to change it to a 1. Tap once more to clear it. When a rule is violated, the offending cells turn red — fix them and keep going. Fill the whole grid without any violations to solve the puzzle.

──── CLEAN & FOCUSED ────
No timers that punish you. No lives to run out of. No pop-ups. Just you, the grid, and the logic.

Whether you have five minutes or an hour, Byna Grid fits the moment.
