About Pentablocks
Pentablocks is an intense bullet-hell dodging game channeling Slopes infamous red blocks and Undertale-style battle evasion. Maneuver your dot with precise WASD controls through endless barrages of sharp pentagonal red obstacles in a neon void. Survive escalating patterns, chain perfect dodges, unlock modes, and hunt high scores in this pure skill-based, addictive browser reflex tester—no shooting, just survival.
It's a focused arcade game made for fans of the genre. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
Two quick pointers before you dive deep: Bank your gains often if the mode lets you — dying with everything un-banked is the classic trap. Stay near the edges in your first few minutes — the center is where everyone fights.
Jump into Pentablocks free on Glaze Games and see how far you can get. No paywall, no install — just open it and play.
