Playdex
What this site is, and what it is not.
Playdex is a set of wikis for idle and incremental mobile games. Each game has its own reference pages — upgrades, currencies, progression trees — with the exact figures, the formulas, and a worked example for each.
The data comes straight from each game's files, not from other wikis. It is checked against the game's code before being published; a value that isn't confirmed is flagged as such. The guides make clear what is advice and what is fact.
Playdex is not official and is not affiliated with any publisher. Each wiki links to the official game on its store: the best way to support a creator is to play their game.
