Antimatter Dimensions — free online Open Source game
Buy dimensions, reset for boosts and watch the numbers explode.
Antimatter Dimensions is a free online incremental game about numbers that grow far past infinity. Buy eight tiers of dimensions that produce one another, reset for boosts and galaxies, then break infinity, enter eternity and unlock challenges, time studies and a full automation scripting language. The game is designed to be played over months and reveals new layers long after you think you have seen it all. Antimatter Dimensions is open-source software by IvarK and contributors; play it in your browser with no download and no sign-up.

Quick start
- Press start and buy your first Antimatter Dimension.
- Use the antimatter it makes to buy the second dimension, which makes more of the first.
- Buy tickspeed upgrades to make everything run faster.
How to play Antimatter Dimensions
- There are eight dimensions. Each one produces the dimension below it, and the first one produces antimatter.
- Buying ten of a dimension raises its multiplier, so buying in sets of ten pays off.
- A Dimension Boost resets your dimensions in exchange for a permanent multiplier and access to more dimensions; Antimatter Galaxies make tickspeed upgrades stronger.
- Reach about 1.8e308 antimatter to go Infinity. That big reset gives Infinity Points to spend on upgrades and opens challenges.
- Later layers add Eternity, time studies, an automator with its own scripting language and much more.
Controls
- Play with the mouse: click to buy dimensions, upgrades and resets.
- M buys as many dimensions and tickspeed upgrades as you can afford.
- The game's options list every hotkey and let you change notation and other settings.
