Free to download: explore five islands, merge gems in the Gem Workshop and fill the Number Atlas. One purchase unlocks the full game. No ads or subscriptions. Every gem is a number. Every shared factor opens a possibility. Swap adjacent gems to line up four or more with a common prime factor. Matching divides each number by that factor. When a gem reaches 1, it clears; falling gems can set off another chain. For example, 2, 6, 10 and 14 share the factor 2. After that division, the 2 clears and the other gems become 3, 5 and 7. Look beyond identical numbers to find your next move. AN ADVENTURE IN NUMBERS Explore 50 levels across five floating islands. Work with a 30-move budget, chase three score stars and take on gem challenges. Anchored gems add a new twist: you can reduce them, but you cannot swap them. MAKE YOUR NEXT MOVE COUNT Earn +1 and −1 runes to change a gem's number, and rainbow runes to remove a chosen prime factor across the board. The first three hints in a level or run are free; each additional hint costs one move. A board with no legal move shuffles automatically. UNLOCK ENDLESS CHALLENGE Clear all 50 adventure levels to unlock Endless Challenge. Start with 20 moves and earn more through scoring. Each new score-earned move requires more points; the progress bar tracks your next move separately from your total score. Clearing five large gems also earns a move. GEM WORKSHOP From level 6, clearing levels rewards you with gems. In the Gem Workshop, merge two gems into their product (8 × 7 = 56), split a gem back into its factors, or shift one with rare +1 and −1 gems. Can you collect all 256 gems, from 2 to 257? COLLECT AND EXPLORE Every gem you collect unlocks a short real-world story about its number in the Number Atlas, like opening a fortune slip: a piano has 88 keys; Halley's Comet returns about every 76 years. Share a collected gem or a cleared level as a picture card. Turn on optional gem-layer rings that show each gem's factors. Play in English, Simplified Chinese, Traditional Chinese, Spanish, Brazilian Portuguese, French, German, Japanese or Korean. FREE TO START, PLAY OFFLINE Free to download. A single one-time purchase unlocks the full game. No ads or subscriptions. No account required. Play offline; progress is saved on your device. Factor Gems is the debut game from a two-person team building games in their spare time. The team comes from education backgrounds and wanted to make the relationships between numbers feel active, visual and playful.
