Cube Smash 3D is a sunny-meadow survival game in the browser: grumpy cube blobs hop toward you from the treeline, and your Smash Hammer swings automatically whenever one is in range. Level-up picks add two more auto-weapons - orbiting Spin Blades and lobbed Boom Stones - plus boots, heals, magnets, and regeneration. A crowned Boss Blob with its own health bar charges in every couple of minutes, and the meadow cycles from bright day to firefly-lit night as you survive.

Welcome - press Play to load Cube Smash 3D. The whole game runs in your browser: about 610 KB downloads once (mostly the shared 3D engine), then it is cached, and best scores stay on this device under ftol:cubesmash3d:best. Nothing is uploaded and no account is needed.
The loop is the classic survivor rhythm: cube blobs hop toward you across a sunny low-poly meadow, the Smash Hammer swings automatically whenever one is in range, and the gems they drop fill the level bar. Each level up pauses the action and offers three picks from a pool of eight - including two whole extra weapons, orbiting Spin Blades and splash-damage Boom Stones - so every run builds differently. Bigger dark-green blobs arrive after the first minute, a crowned Boss Blob with its own health bar charges in every couple of minutes, and the day rolls into a firefly-lit night with faster spawns - the meadow always wins eventually; the score is how long and how loudly you resisted.
Desktop plays with WASD / arrows, SHIFT to sprint, SPACE to jump, mouse drag to orbit the camera and scroll to zoom; P pauses and M mutes the small synth sound effects. On touch, drag to move and tap to jump. When the health bar empties, Play or R restarts instantly.
Frequently Asked Questions
What does Cube Smash 3D do?
It is a hammer-survival game: cube blobs hop toward you on a sunny meadow, your Smash Hammer swings automatically at anything in range, and smashed blobs drop gems and coins. Gems level you up; each level offers a choice of three upgrades. The run ends when your health bar empties.
Does it work on a phone?
Yes. Drag to move and tap to jump - the hammer already swings on its own. A keyboard (WASD / arrows, SHIFT, SPACE) plus mouse camera control gives finer play on desktop.
Is anything saved in my browser?
Yes. Your best score uses localStorage key ftol:cubesmash3d:best. Nothing is uploaded - the game runs entirely client-side.
What do the upgrades and weapons do?
Each level up offers three picks from a pool of eight: Heavier Hammer, Quick Swings, Spin Blades (a NEW weapon - blades orbiting your character, growing +1 blade per pick), Boom Stones (a NEW weapon - splash-damage stones lobbed at the nearest blob), Swift Boots, Hearty Meal, Gem Magnet, and Thick Skin. Owned weapons show as badges with up to eight upgrade pips each.
What is the Boss Blob?
Every couple of minutes a crowned, oversized blob storms in with its own health bar under the timer. It periodically charges at high speed, hits harder than normal blobs, and bursts into a shower of gems and five coins when smashed.
Why does it get dark?
The meadow runs a day-night cycle of about two and a half minutes per day. At night the sky darkens, fireflies come out, butterflies rest, and blobs spawn about 20% faster - the clock in the corner shows Day or Night.
