Exponential Idle vs Incremental Mass Rewritten
Both are pure numbers, prestige incrementals. Here's how they differ, from the same data we use everywhere on IncrementalGames.org.

Exponential Idle
A math idler where the upgrades are literally terms in an equation. Graduate, then play the custom theories.

Incremental Mass Rewritten
DormantGain mass, become a black hole, then an atom, then a supernova. The numbers get absurd quickly and never stop.
The short version
- Exponential Idle is the more idle of the two (leans idle); Incremental Mass Rewritten asks for more hands-on play.
- Incremental Mass Rewritten is completely free; Exponential Idle is free-to-play with purchases.
- Incremental Mass Rewritten stacks more prestige layers (8 against 2).
