IRON SMASH

Iron Smash is a free online physics-based arcade game where you swing a heavy iron flail to destroy relentless waves of geometric enemies. You control the chain with your mouse, building momentum to send the iron ball crashing through anything in its path. Every hit, every combo, every enemy cluster you wipe out feeds directly into your survival run.

As you rack up kills, enemies drop XP that powers up your character between waves. Upgrades are random, so every run plays differently – you might grow your ball to a ridiculous size, stretch your chain to cover the whole screen, or crank your speed so high the physics go completely chaotic. Mastering the swing is the real skill here: learn to arc your flail around corners, use walls to redirect momentum, and time your sweeps to chain multi-kills for maximum XP income.

If you enjoy browser arcade games, survival games with roguelite upgrades, or physics sandbox chaos, Iron Smash delivers exactly that with zero friction – no download, no login, just play. Fans of ball-and-chain games, 2D action arcade games, and wave survival challenges will feel right at home. Search terms like 'free flail swinging game', 'physics ball arcade game online', and 'survive wave shooter browser game' all lead here for good reason. Jump in, swing hard, and see how many waves you can clear.
