Number Climb

Tap to grow a number, then buy machines that build machines that build your number. Reach one million and ascend for a permanent bonus.

How to play

Tap the big button to add to your number. Every ten machines you own also raise how much each tap adds.
Buy a Counter to make your number climb on its own. Each machine tier makes machines of the tier below it, so one Factorial slowly feeds a whole chain.
Costs rise a little with every machine you buy, so mix the tiers rather than stacking only one.
When you have climbed to one million in a run, Ascend. You restart from zero but keep permanent ascension points, each worth +50% of everything.

Buy a few Counters first, then start the Doubler tier. Chains pay off slowly but then take over.
Ascending early gives a small bonus. Pushing a little past one million gives more points, because the reward grows with the square root of your run.
Your progress keeps running at half speed for up to an hour while the tab is closed.
The game saves automatically in this browser. Reset progress erases everything including ascension points.

Does it keep going when I close the page?: Yes, at half speed for up to one hour. A summary shows when you come back.
What does Ascend do?: It resets your number and machines in exchange for permanent ascension points that multiply all income and taps.
Is anything saved online?: No. Everything stays in this browser.
