A Game About Digging A Hole™ vs Uncontained

Dig deep, sell what you find, update your equipment to continue your journey further and further. With every spadeful you dig, you get closer to the truth. There's no rush, no rules - just you and the adventure underground. Costs as much as a coffee, but is fun for longer!

UNCONTAINED is a nuclear fission puzzle game where every split counts. Touch an atom, pull back to aim, and release to fire neutrons. Chain reactions cascade through the board — clear every atom to advance. FIRST 10 LEVELS FREE Master the fundamentals of fission with 10 free levels. Unlock the full game to access all 72 levels across 6 chapters, and watch a verified solution for any level you're stuck on. 9 ATOM TYPES Uranium-235 splits on impact. Plutonium-239 chains at any speed. Deuterium triggers fusion shockwaves. U-238 absorbs your neutrons. Californium-252, Thorium-232, Tritium, Antimatter, and Strange Quark Matter each introduce unique behaviors. 5 LEVEL MECHANICS Reflector walls bounce neutrons. Gravity wells bend trajectories. Tamper shells contain blasts. Flux zones accelerate particles. Cascade fields prime atoms for chain reactions. THE CASCADE The level map is the explosion. Solve a level and it detonates into the next ones, until all 72 light up as one full blast. CINEMATIC DETONATION Your cumulative yield powers an escalating detonation sequence — from reactor breach to supernova to vacuum decay. 8 tiers of destruction with cinematic animations, haptic feedback, and procedural audio. 51 GAME CENTER ACHIEVEMENTS Track your mastery across chain records, yield milestones, atom-specific challenges, and hidden secrets. FEATURES — Slingshot aiming with real-time trajectory preview — Procedural audio engine — every sound synthesized in real-time — Metal GPU shaders for atom glow and shockwave effects — iCloud save sync across devices — Game Center leaderboards and achievements — No ads.
