Diep.io Unblocked at 77: Tanks, Trees & True Heirs
Updated 2026-10-22 · Unblocked Games 77 Team
The tank that invented a subgenre
Diep.io took the io formula and added the thing it was missing: builds. Your tank levels, you pick stat upgrades, the upgrade tree branches into classes — sniper, machine gun, overlord — and suddenly a shape-shooter has theorycrafting. Of the original io trinity (cells, snakes, tanks), diep aged best because its depth was mechanical rather than cosmetic.
The official diep.io still runs and is often reachable; when it isn't, the subgenre it spawned carries the torch.
Shape-shooting on the 77 shelves
The aim-and-upgrade core translates across our shooting shelf: Blocky Shooter for geometric combat, Elemental Barrage for bullet-pattern chaos, Stellar Bastion for the defence-build brain, and Tank Push for literal tanks. Arena instincts live on the io shelf — full tour in the io guide.
If you're here for loadout-tinkering specifically, Stellar Bastion is the sleeper pick: its tower trees scratch the same class-building itch as diep's level-45 decision.
