The 20-Egg Problem

The 20-Egg Problem is a simple, fast, and challenging arcade-style game. It started from a mathematical curiosity: on a grid of 100 cells, there are roughly 535 quintillion different ways to place 20 eggs. Every round the eggs move to new spots, and you dive into that huge universe of combinations to find them all in the least time possible. Tap the grid to mark where the snakes should look. They crawl there on their own: if an egg is there, it appears; if not, the cell turns into a hole and the snake reappears far away. Every guess counts as one try, and a snake that bites its own tail ends the round. Key features: • Find the 20 eggs hidden on the 10x10 grid • Play with 1 or 2 snakes — up to 5 with the optional unlock • Adjust the snakes' speed • Track time, tries, and eggs found • See your best time, medals (gold, silver, bronze), and perfect games • Minimalist black-and-white look with color accents, inspired by classic arcades • No ads, no account, no data collection Easy to understand, hard to master. A single optional purchase unlocks 3 to 5 snakes for anyone who wants a bigger challenge.
