Fruit Fly Idle

One fruit fly on a clean white screen. That is where everything begins.

Feed your colony and improve reproduction to watch more flies appear on the actual screen. Balance births and deaths, survive dangerous traps, and turn an empty display into a buzzing swarm.

• Simple idle growth starting from exactly one fly • A visible swarm that grows and shrinks with your population • Upgrade food, reproduction, lifespan, and trap resistance • Replace generations and spend genes on permanent progress • Collect 100 distinct rare flies, including royal, ninja, robot, and angel flies • Captured rare flies join your catalog and can appear in the swarm • Automatic local save with no account or game server • Korean, English, Japanese, and Traditional Chinese

Optional rewarded ads provide stackable, time-limited auto trap removal, reproduction boosts, and rare discovery boosts. The game remains playable without watching ads.
