About this game

◆◇A challenge from game designers to all of humanity◇◆

Are you capable of getting a ball out of a cup?
If you are confident that you can, we challenge you.
It may sound simple, but the truth couldn't be further.

◆◇How to play◇◆
Take on the challenge by creating a solution on the screen to clear the Q.

“Oh man, this is hard.”
"The solution differs greatly from person to person."
”Unique and multiple solutions!”
"There are Q's that even we developers cannot solve."

Interested? We challenge you to complete the Q. Our Q’s are so exciting, we promise to keep you engaged until you lose track of time.

◆◇Share your Victory◇◆
Share your victory with the rest of the world.

◆◇Using SNS◇◆
Be the first! Share your victory moment on Twitter, Facebook and other social media.

3) You will be able to see how many people in the world have managed to solve each problem.

The puzzles are enjoyable enough but the excessive ads, and I mean an ad after every puzzle is ridiculous. Uninstalled after only a few minutes. Also it wants access to photos and stuff which is kinda sus. Only played it here because it's not on switch where I am. Gonna find a way to play the switch version instead.

The puzzles were enjoyable but 1: The game is VERY sluggish and laggy, seems like it was a last minute port to mobile considering how much it lags sometimes, not to mention you won't get smooth lines around 50% of the time 2: It just cuts your line of the moment you even get NEAR a box or the wall, and it's very infuriating because the game just feels like it's going against you by making it hard to draw lines around containers and walls 3: too many ads all the time after any level, 30sec ad

Coming here after watching hololive girls' play. I find it interesting and tried to play. The game concept is really fun. But the intrusive ad which appears whenever you passed a single level is ruining the mood to play. Well, I'm not planning to get a switch anytime soon. But I'll consider to buy a pc release because I have a graphic tablet to use.
