Stumble Guys

The fastest way I found to complete levels actively or semi-afk is by loading a three round custom game of only Space Drop (or any of the hexagon tile variants) with bots and simply jump around for a bit to blow through rounds or lose and reset. You won't get any stars, trophies, or XP, but in exchange you get rapid progress to the achievement; you choose.

If you want XP and stars, you can simply load public games and AFK at the start (or play if you care to) and progress that way. That being said, I would only recommend these lazier options to achieving this if you already have all other gameplay achievements acquired and the current battle pass (F the cosmetics).
