Inspiration

Fungy Sudoku was born from a simple idea: to make the classic, quiet Sudoku come alive. We wanted to bring motion, tension, and playfulness into a game known for its solitude — turning logic into action. And make players compete on a shared grid.

What it does

In Fungy Sudoku, numbers turn into colorful mushrooms. Players plant different colors to fill the grid — no color repeats in each row, column, and block. On a shared multiplayer board, everyone races for points: whoever completes a unit first takes the bonus. You might plant two, but if another player finishes the line, they score. You can shovel others’ mushrooms or use mischief items to stall rivals.

How we built it

Fungy Sudoku builds on the core logic of the other horizon game we've been working on-Fungy Boom, adapting its:

Grid validation and conflict-checking algorithms
Planting, shovel and camera mechanics
Multiplayer synchronization layer for real-time score competition

Challenges we ran into

Game design: ensure fairness and responsive feedback
The multiplayer scoring system without time limits
Making the rules instantly clear

Accomplishments that we're proud of

Turned the traditional puzzle game into a lively, shared experience
Created a world that feels playful and fun with vivid visual and sound feedback
A connected Fungy ecosystem, where experiences, rewards, and player progress intertwine across multiple games

What we learned

Balance in multiplayer Sudoku isn’t about symmetry — it’s about giving everyone a fair chance to feel clever.
