Echo is a puzzle game built on real open problems in mathematics. Each puzzle is a graph: dots joined by red and blue lines. Your job is simple to learn. Tap a line to flip its color, and break up the "bad cliques" - groups of dots all wired together in a single color. Clear them within your move budget and the puzzle is solved. Here is the twist. Every puzzle is a slice of a genuine research graph, and every solution you find is committed to a shared, growing proof tree. When you solve, your result seeds a brand new puzzle for another player. Their solve seeds the next. Together, the whole community is searching for colorings no person and no computer has ever found. You choose which problem to work on from the home screen: - R(4,4), the practice board - solved long ago, so the search genuinely finishes and you can see the whole engine work end to end - R(4,6), the frontier - an open problem where reaching zero would set a real new record - R(5,5), the legendary one - open for decades, where the prize is the lowest count the network has ever driven it to You do not need to know any of that to play. If you can spot a pattern and tap, you are already contributing. FEATURES - Quick, tactile puzzles you can finish in a minute - Three problems to play, from a winnable warm-up to a famous unsolved one, switchable any time - Five ways to view each graph: circle, spectral, matrix, hub, and density - switch any time to see the structure differently - A living progress screen showing the community's best reach and the proof tree growing in real time - Your lineage: see how many puzzles your solves have seeded for other players - A built-in glossary that explains every term in plain language - No ads, no timers, no pressure Color the graph. Advance the proof. Echo forward.
