What the Buck?! is an incremental game.
The Idle category on UBG76 collects nine incremental and clicker games where small actions turn into bigger numbers and better upgrades. You can mine blocks in MineCash, catch fish in More Fish Idle Clicker, type out Moby-Dick in TL;DR or grow a startup into an empire in Rise of the Mogul. It suits players who enjoy steady progress and like to check back on a game between other things.
UBG76 has 9 idle games right now, newest first.

Idle games keep earning while you are away, and incremental games center on numbers that grow with every upgrade. Most games here mix the two: Hidden Grimoire: Idle Alchemy gives up to 8 hours of offline progress, while TL;DR and Slice To Meet You pay out when you type or slice.
Six of them are free demos. Feed the AI, MineCash, More Fish Idle Clicker, Slice To Meet You, TL;DR and What the Buck?! have a browser demo, and the full game is sold on Steam or is coming there. Hidden Grimoire: Idle Alchemy and Rise of the Mogul are still in development, so their systems can change between updates.
No, every idle game here opens in a new tab on the page where it is published. That is itch.io for eight of them and CrazyGames for Plinko Idle.
