How I Built a Solvable ‘Sheep’ Puzzle Game and Open‑sourced It

Hello, I'm Su San, sharing a fun mini‑game I developed.

The popular “Sheep Sheep” puzzle went viral, but its random generation makes higher levels almost impossible to clear, turning it into a luck‑based game.

Motivated, I built my own version called “Fish Fish”, open‑sourced it, and posted it online.

The game offers multiple difficulty levels and customizable settings such as slot count and blocks per level.

Four key implementation points:

Global parameters are stored as unified variables, allowing easy adjustments and user‑customizable settings.

The canvas is divided into a 24 × 24 virtual grid; each block occupies a 3 × 3 cell area.

Blocks are generated randomly: patterns are shuffled and placed, while coordinates are chosen within a shrinking range as levels increase, raising difficulty.

Block layering is handled by assigning a level attribute; overlapping blocks are linked during generation so that higher‑level blocks must be cleared first.

These choices are not the only possible solutions but they satisfy the game’s functional requirements.
