SLICE and STACK — The Precision Cutting Game Slice beautiful 3D objects in half with surgical precision. Choose from 30 unique blades, master 50+ real-world materials, and build the tallest tower from your cut pieces. SLICE IT Draw your cut line across stunning 3D objects — jade, crystal, diamond, plasma, and more. Every material behaves differently. Use water cooling for hard materials, pick the right blade, and aim for the perfect 50/50 split. STACK IT Every piece you cut gets stacked onto your tower. Choose wisely — bigger pieces score more points but can destabilize your tower. Balance risk and reward as your tower grows taller with each level. 30 UNIQUE BLADES Start with a Laser and Katana, then unlock Diamond Saw, Plasma Cutter, Ice Blade, Flame Sword, and 24 more — all the way up to the devastating Big Bang blade. Each blade cuts differently with unique visual effects, trail patterns, and debris. 50+ REAL MATERIALS Cut through Oak Wood, Granite, Gold, Crystal, Obsidian, Ruby, Diamond, Plasma Core, Meteorite, and more. Each material has real-world density, hardness, and friction that affects how your blade performs. LEARN WHILE YOU PLAY Every material and blade comes with fascinating real-world science trivia. Did you know diamonds form 100 miles deep under 725,000 PSI? Or that a katana's edge has 65,000+ layers of steel? 4 GAME MODES • CLASSIC — Slice & Stack through 55 levels of increasing difficulty • ZEN — No pressure, just relaxing cuts at your own pace • CHALLENGE — Multi-cut targets with tight tolerances • DUEL — Compete against phantom rivals for precision bragging rights FEATURES • Stunning 3D objects rendered in real-time • 8 unique scale types for weighing your cuts • Tower stability physics — keep your stack balanced • Hint system with smart 50/50 cut calculation • Water cooling system for hard materials • Beautiful neon noir visual style • Works in portrait and landscape on iPhone and iPad • Real science trivia for every material and blade Free to play with optional rewarded ads for power-ups, hints, and water cooling.
