Tiny Fishing is an idle fishing game with one input. Tap to cast, and your hook sinks; on the way back up, drag it left and right to snag as many fish as you can, with deeper, rarer fish worth more. Sell the catch, buy a longer line, more hooks and a bigger boat, and cast again. It is calm, it is quick, and it is one of the most-searched casual games on this site.
The loop is small enough to play in a spare minute and the upgrade curve is tuned so there is always one more thing to buy. Money accumulates while you're away thanks to an offline earnings mechanic, which is why people keep coming back to it between classes.
