Prism Fall: Idle Geometry

Watch the shapes fall.

Prism Fall is a quiet idle incremental. Neon polygons drop down a dark column, bounce off rotors, geysers and springs, and land on gates. Every shape that lands pays out. Spend what it pays, unlock the chamber below, and let it run.

No aiming. The shapes fall and pay on their own. One screen, one hand, and numbers that keep climbing.


EVERY AD IS ONE YOU CHOSE

No interstitials. No ad when you open the app. No banners. Every ad in Prism Fall sits behind a button you press for a bonus you asked for, and you can ignore every one of them and still finish the game.


KEEPS PAYING THROUGH THE NIGHT

Prism Fall keeps paying while you are away. You earn your full rate for the first two hours, then a reduced rate, for up to 8 hours - a full night's sleep. With the optional Auto-Collect upgrade there is no reduced rate and no 8-hour limit, and it keeps counting for up to 90 days. Come back after a night and the app shows you what was waiting.


EIGHT CHAMBERS DOWN

DRIFT. ROTOR. SWITCHBACK. KICKERS. THE LADDER. GEYSER. SPRINGWORKS. THE LOCKS.

Each chamber is built around one obstacle and only one, so shapes fall through each of them differently. Buy your way down and the column gets deeper every time.


WHAT YOU BUILD

- 15 shape types: four polygons, seven stars, then four curves. Triangle to Bloom, and each one has its own upgrades
- A shape codex: every shape you have found, and what it takes to reach the rest
- 5 upgrade tracks: shape value, spawn rate, fall speed, gate width, and an impact bonus that pays you for bouncing off the obstacles
- 20 collectible cards, drawn with Prisms and levelled with fragments that drop while you play. You keep them through every Collapse
- 12 perks, with three new choices every run
- Two layers of prestige: Collapse for Cores, then Singularity
- A daily gate that pays Prisms and fragments when you fill it, and a surge that turns up when it feels like it


BUILT FOR SHORT SESSIONS

Open it, buy an upgrade, close it. Or leave it running and watch the column for ten minutes because it is nice to look at. Both are the intended way to play. Minimal geometry, a deep dark palette, and physics you can watch instead of a spreadsheet you have to read.


NO ACCOUNT TO CREATE

The game plays offline. It never asks you to make an account, or for your email or your friends list. If you are signed in to Google Play Games, your progress is also saved to the cloud, so a reinstall or a new phone picks up from your last cloud save. Notifications are few: one when your full offline rate ends, one when daily missions reset, one when a new season starts, and up to five reminders over your first week away. Quiet hours, on by default, hold anything due between 10 PM and 9 AM until morning, and a single switch in Settings turns notifications off entirely. There is no energy bar and there are no lives.


OPTIONAL PURCHASES

Four one-time upgrades - rewards without the ads, offline income at full rate with no 8-hour limit, double Shard income, and a starter bundle - plus Prism packs, a Prism Vault that fills as you Collapse, and an optional pass during seasonal events. None of them unlock content you cannot reach by playing, and none of them are required to finish anything.


A relaxing, minimalist idle game for people who would rather watch a physics simulation than tap a cookie.

Come back whenever.
