FyraNollFyra is a mathematical puzzle game where the objective is to spell out 4, 0 and 4 in three containers. To do so you need to move numbers and operators until the equations in the containers reach their desired result.

A total of six trophies are hidden throughout the three sections of levels and the tutorial.

There is a hint function to assist you if you get stuck. Coil subscribers get the 10th of the normal cooldown until the hint function get ready again after use.

The game is adapted for mobile devices. To achieve the best result on tablet or mobil, allow the game to be installed on the start screen as a Progressive Web App (PWA).

Fyra noll fyra means four zero four in Swedish.

Feedback from the experts

Nathan Lie: Simple puzzle game that ties in nicely to the theme for the jam. The Web Monetization bonus is nice - it's just the right balance between helpful and not detrimental to the gameplay experience. I would suggest some sound or music to help create an atmosphere while playing.

Anselm Hook: Nice game. Coil support is nice.

Ewa Mazur: I like the progresive difficulty and the idea of faster cooldown of hints for Coil subscribers. I'm not a big fan of a color palette, but it seems like a subjective problem.

Christer Kaitila: It was such a thoughtful touch to warn about strobe flashes and allow players to turn them off! Wonderful extra polish. I was also really impressed by the level preview thumbnails! What a cool feature. The way you can move parts of each equation around was really unique and interesting. My mental math skills were so poor that I found most of the puzzles beyond my capabilities but I could see someone absolutely loving every last one of your amazing puzzles! Excellent work!

Jupiter Hadley: Clever maths game! It's got great graphics.
