Play Archachain Online
You set off one explosion, then tweak angles and upgrades as the chain reaction spirals into beautiful chaos—just don’t panic-click or everything flies apart.

Note: Right click and select full-screen for best experience
Game Overview
Archachain is one of those weirdly satisfying chain reaction games where you set off a single explosion and watch everything domino in the most ridiculous ways. At first, the upgrade system feels like overkill—why does my explosion need tiers?—but after a few rounds, you’re totally hooked on tweaking angles and timing.
The tutorial’s actually helpful (shocking for a Flash game), though I still messed up my first few attempts by spamming abilities too early. Left-click reverses your rotation, which sounds simple until you panic-click and send your chain spiraling into oblivion. And yeah, the "do it for the children" bit never gets explained. Just roll with it.
Hot tip: Bind your abilities to keys 1-5 unless you enjoy frantic mouse juggling mid-chain. Things get gloriously chaotic fast.
