Grab Droid-ify (F-Droid alternative front end) while you're there, and add some of the additional repositories it supports (such as IzzyOnDroid) for a wider selection.

ETA some of my go-to time wasters:

• Vector Pinball
• DropCount
• Fruity Game
• Apple Flinger
• Doors of Doom
• Gurgle (Wordle clone)
• Ball2Box
