Gridflow is a logic puzzle that appears daily — quiet, precise, and without distraction. Connect numbered nodes with bridges. Each node dictates exactly how many bridges must connect to it — not one more, not one less. Bridges run horizontally or vertically and may not cross. In the end, the entire network must be connected. Easy to learn. Hard to master. FOUR DIFFICULTIES. EVERY DAY. ALL OF THEM. Easy (5×5) — Two minutes of focus. Perfect for the morning. Medium (7×7) — Challenging without being frustrating. Hard (9×9) — When you really want to step outside your comfort zone. Expert (11×11) — No mercy. For those who want it that way. Four fresh puzzles every day. An archive of past weeks. Your streak counts. NO TIMER. NO PRESSURE. NO ALGORITHM. Gridflow doesn't reward speed — it rewards finishing. The app gives you three hints per day. Needing one isn't failure. No scoring system that compares you to others. No feed to distract you. No subscription designed to exploit forgetting.
