GeoTess: Asteroid Puzzle

In this original blocks game, matched shapes do not clear. That is the rule everything else follows from. Line up tiles of the same color into one of eight target shapes to gain access to new powerful devices sitting on the board, waiting. You choose when to use them to clear tiles from the board. This game is free; it has no ads, no in-app purchases, and you can play it offline for as long as you want (endless missions). A BOARD WITH NO EDGES GeoTess is played on an icosahedral geodesic asteroid: 180 triangles, and nowhere to get stuck. Every board game has a border, but this one has no end, so a shape can run off in any direction and wrap around the other side. A row on this sphere is not exactly a straight line, and each triangular tile connects to 3 rows, not the usual 2 rows on 2D boards. There are 18 of these rows, each exactly 30 triangles long, and every triangle sits on exactly three of them. Send a Digger device along one, and it grinds the whole way around the asteroid, back to the tile it started on. TWELVE CRATERS WITH GEOMETRIC ANOMALY On a flat grid of triangles, six meet at every point. On a sphere, that is impossible. Math (Euler's formula) guarantees that any triangulated sphere has exactly twelve points where only five triangles meet, and that makes the game much more interesting! Those twelve anomalies are the craters, and they are the only places a Fabricator device can be built. The most valuable device in the game exists because of a constraint that mathematics placed there. EIGHT DEVICES, AND WHEN TO SPEND THEM Fuse, Charge, Blast, Digger, Thrower, Gambit, Drones, Fabricator. Each is earned by a different shape, each clears a different footprint, and each can be upgraded by building on top of it. Activating a device is free. Only placing blocks or swapping neighboring tiles costs a move. That is the whole tension: build too much, and you run out of moves and space; clear too early, and your devices are less impactful (fewer tiles are on the board). In this game, strategy and timing are everything! MISSIONS THAT KNOW THEY ARE POSSIBLE Every mission is generated mathematically to be 100% solvable. Each mission (level) has clear objectives. Clear a specific number of tiles of certain colors, build a specific number of certain devices, or finish the mission with a certain number of active force fields around the craters - that’s your goal, and it changes in each mission. If you get stuck, you can get a hint, and if you want the game to show you how any mission can be solved (beginning to end), just ask - no one likes games that leave you stuck. WHAT IT IS NOT This game has no ads. No in-app purchases. No accounts. No timers, no lives, no energy, no daily streak to keep up. It makes no network calls at all, and collects nothing about you or your privacy: no analytics, no tracking. Your progress stays on your device and in your own iCloud. It was built as a passion project, so just have fun. BUILT TO BE READ A color-blind (Color Vision Deficiency, or CVD) mode adds visual marks on every tile with its own symbol, on the board and interface, where telling colors apart actually matters. Reduced motion is honored. Sound and haptics switch separately. We made an effort to make it accessible for all! We really hope you will enjoy it!
