About This Game

A free AI slop counting game, where the objective is simply to avoid the number 21. Do you have enough brain cells to win?

Detailed Description

Layla is bored and wants to play a game with you. According to her, you must take turns counting upwards in groups of up to 3. But you must count in a way that you don’t end up being the one to say the number 21. 

Actually requires your brain

While her game’s premise is staggeringly simple, it will require the use of some of your finest brain cells to figure out how to beat her. And if you do, you’ll get an achievement. 

Gameplay:

The 'How to play' trailer is for entertainment purposes only. When you actual play the 21 game, Layla will not tolerate any funny business. You can only play by the rules - there are no dialog options for illegal game moves. The goal is simply to beat her 3x in a row for the achievement.

Controls:

Press spacebar to count when it’s your turn.

Included with your purchase:

  • A simple but perplexing arithmetic challenge

  • Single button gameplay

  • Achievements

  • Spoken dialog with subtitles

  • The numbers 1 through 21

  • An annoying girl (ft Layla) 

DLC and extras:

If you've enjoyed counting with Layla, there are some optional donation DLCs available which allow you to take Layla to new locations.
