Up Stack
Stack blocks. Defy gravity. Push your reflexes to the limit.
Inverted Block Stacking
Flip your expectations of physics. In UpStack, neon block slabs rise from the floor and attach to a tower growing downwards from the ceiling.
UpStack is a high-speed cyberpunk arcade game built on precision. As blocks fly side-to-side, tap to lock them onto the growing structure. Any misaligned section is sliced off, making successive placements more challenging. Achieve perfect alignments to generate high-score multipliers and trigger beautiful synthesizer notes, restoring the block's width over time. Can you build the ultimate inverted tower?
Cyberpunk Arcade Mechanics
Antigravity Physics
Blocks rise from the bottom of the screen under inverted gravity, anchoring to the ceiling to form a descending tower.
Precision Slicing
Misaligned block segments are cut off and drop away. Accurate timing is necessary to maintain maximum stack width.
Dynamic Sound Synth
Features an built-in audio synthesizer. Chains of perfect hits trigger chromatically rising retro synth notes synthesized on-device.
HSL Neon Gradients
Blocks shift their color hue dynamically with each layer placed, creating a beautiful glowing rainbow tower design.
Particle Flares
A perfect alignment triggers glowing cyber-blue and neon-red particles that float upwards, adding to the high-tech atmosphere.
