Hole.io is a 2018 physics puzzle game with battle royale mechanics created by French studio Voodoo for Android and iOS.

Players need to utilize the game's real-time physics to their advantage and optimize their path for effective growth.

Additionally, a solo mode exists which allows players to play alone with the goal of consuming as close to 100% of the city within two minutes.

[6] Both games use the same mechanic of a hole in the ground swallowing objects to grow bigger; however, Donut County additionally features a storyline and a cast of characters which Hole.io lacks.

[11] While some reviewers criticized it for copying core mechanics of Donut County,[12] others characterized the game as being "oddly satisfying and addictive".
