  • Grab a ladder and climb to go faster than jumping floor to floor.
  • The lava surges, then stumbles — use the slow windows to climb; your peak height is your score.
  • Crates on a floor block the walk — jump a hurdle, walk a three-crate triangle, or climb a stacked stair to the next floor.
  • Walk into a glowing orb to trigger its power-up instantly.
  • Power-ups activate the instant you touch them — time your route to grab one right when you need it.
  • Tap jump to leap, then re-hold in the air to burn a jetpack; holding through takeoff caps rise at 12 m/s. Fuel is short, leftover dies with the window.

About this game

This is Doomstack’s free climb — an endless, procedurally generated tower of ladders, platforms, and rising lava. Climb as high as you can before the lava catches you; there’s no timer beyond that. Use the on-screen controls on touch devices or the keyboard on desktop to move, climb, and jump. Your height at the moment the lava reaches you becomes your score for that run. Sign in to save your best run permanently to the free leaderboard at /climb — you can also play as a guest, though guest runs aren’t recorded. Every run can be shared as a replay link so someone else can watch exactly how you climbed. The free climb is entirely skill-based: no payment, no way to pay for a better rank. Prefer a head-to-head? Race another climber in 1v1 duels — same tower, same rising lava, one winner. See the rules for details.
