### 5/5 — Exponent idol

*2026-08-02, version 1.4.40*

Still blown away that this game is fundamentally astonishingly fun

### 5/5 — Worth the investment

*2026-05-28, version 1.4.40*

Phenomenal game. No unnecessary ads. One purchase for permanent ad block ($2!) and a silky grey atmosphere. Wonderful idle experience overall. Highly recommended.

### 5/5 — Honestly, its really fun

*2026-05-26, version 1.4.40*

I love the incorporation of math in an Idle game. I’ve seen something similar before, but never to such a degree. Bravo

### 5/5 — Awesome game but 1 thing...

*2026-05-21, version 1.4.40*

Awesome game but r9 swapping is a huge pain - auto r9 swapping needs to be an unlocking feature. Make it parameterized - % of last max, amount of time, etc. until next prestige or supremacy.

### 5/5 — Best incremental game

*2026-05-20, version 1.4.40*

The mini games are honestly my favorite, they are so clever. The idle game mechanics of exponential idle are amazing and endless, too.

### 1/5 — Don’t waste money

*2026-05-07, version 1.4.40*

Constantly need to restore purchase, constantly getting hours of offline rewards nerfed due to my purchase not being restored. Very disappointing to have one crucial IAP and it’s barely functional.

### 5/5 — Great Idle Game

*2026-04-29, version 1.4.40*

So much fun playing this idle/incremental game. Loved the theme of it and the fun little tweaks on the idle format.

### 1/5 — If you wanna waste your life by all means download

*2026-04-21, version 1.4.40*

Awful progression 100% don’t recommend

### 5/5 — good game

*2026-04-07, version 1.4.40*

I love exponents

### 5/5 — Really great and well-thought out game

*2026-03-23, version 1.4.40*

Probably the best idle game out there that I’ve played. As a working mathematician, it’s really cool to see a game which has somewhat mathematically in-depth mechanics, as well as a storyline which is very relatable to those going through the academia pipeline. Highly recommend!
