The ultimate founder launchpad: Cap tables, equity & 409As

Hey Product Hunt 👋 I'm the solo developer of Guriddo (グリッド, Japanese for grid) and looking for your feedback 🙂 What started as a small programming challenge has become a time consuming (but still fun) side project that regularly keeps me up late at night. At the moment Guriddo has around 300 active players, so If you enjoy playing number/logic puzzles, I urge you to give Guriddo a try. The rules of Guriddo are similar to Sudoku: You have a 9x9 grid that can be filled with numbers from 1-9, however there are no subgrids. The grid is divided by tricky black fields. But see for yourself. Features: 📅 Everyday I release a new puzzle (daily challenge) 📋 Track your solving time and compete against other players (leaderboards) 🧠 There are 5 different difficulties (easy to diabolical) ☕ Take a break from the daily challenges and select your own difficulty (coffee break) 🌊 Invite your friends & compete against them (onsen party) 👀 Profile with stats about your skill level & progress 📦 Packs with hand-selected puzzles (e.g. for beginners) 📖 Guide with solving strategies If you have any further questions, suggestions, praise or criticism, do not hesitate!

Thank you for this glorious game. Been a regular from the start of this year.
