Wrist Ninja — Slice. Train. Ascend. The original Apple Watch fruit-slicing game is back — bigger than ever on iPhone and iPad. Swipe to slice, dodge the bombs, build combos… and earn your place in Master Poo's Dojo. WELCOME TO THE DOJO An all-new world with hand-crafted art. Your sensei is watching. Train hard, earn shurikens, and climb from white belt to black. DOJO JOURNEY 60 levels across six belts. Slice trials, survival gauntlets, score challenges — and a boss battle at the end of every belt. Three stars per level. Earn them all. TEN REALMS TO MASTER Every realm is a full world: its own fruit, its own arena. Slice through the Orchard Dojo, the Neon Night Market, the Chaos Rift, the Golden Palace, and more. Unlock realms with skill or shurikens — or grab everything at once with a single purchase. SIX WAYS TO PLAY Free Play — Classic survival. No clock, no mercy. Arcade — 60 seconds. Slice everything. Zen — No bombs, no pressure. Just vibes and fruit. Daily Trial — One seeded run per day. Same fruit, same bombs, same shot for everyone. Global leaderboard. Clan Tournament — A new seeded run every Monday. Seven days to climb. Dojo Journey — The campaign. Belts, bosses, glory. EARN SHURIKENS Every slice pays. Spend shurikens on realms, blade trails (Shadow, Gold, Sakura, Fire, Rainbow), continues, boosters, and streak protection. Collect your daily Training Stipend just for showing up. SENSEI'S ORDERS Three fresh missions every day, plus a cross-device challenge that spans your wrist and your phone. Everyone gets the same orders. Not everyone completes them. APPLE WATCH The original. Slice on your wrist anywhere — scores, quests, and shurikens sync to your iPhone automatically, and the complication tracks your progress right on the watch face. CHALLENGE YOUR FRIENDS Send a challenge in iMessage. They play, you rematch, the bubble keeps score. Ties are dishonorable. GAME CENTER Global and weekly leaderboards, 13 achievements, personal bests, and win streaks across every device. No ads? No problem. One purchase removes all ads permanently, on every device. Wrist Ninja is free to play. No subscriptions. No pay-to-win — shurikens never buy score, only style. Just your reflexes against an endless stream of flying fruit. The dojo asks little. The dojo asks you.
