Hey Product Hunt! I'm Gray, maker of Balance Grid. I kept failing to stick with brain-training apps because sessions were too long — so I built the opposite: one 6×6 Takuzu grid a day, solvable in about two minutes with pure logic (no math, I promise). There's a daily challenge, 18 practice puzzles, and a tutorial that teaches the deduction rules from scratch. It's free, no sign-up, runs in the browser. I'd love your feedback — especially on difficulty curve: should the daily start easier through the week? Happy to answer any questions!
