Bloom Chain

Bloom Chain is a cozy hex puzzle about chain reactions. Made in Defold for the Defold Game Jam 2026 (theme: CHAIN REACTION).

How to play

• Drag a seed stack from your tray onto an empty tile (or tap the seed, then the tile).
• Same colours slide together. 7 of a colour bloom.
• A bloom grows every neighbouring stack by one — so a stack of 6 next to it blooms too... and the next, and the next.
• Hit the chain goals (×2 → ×3 → ×4 → ×5) to bring the garden back. Every goal gives you +8 turns.

The trick

Don't pop small blooms early. Line up stacks of 6, then set one off. While you drag, the tile shows the chain you are about to cause (×n) and the tiles that will bloom glow gold.

Scoring

The k-th bloom in a chain scores 100×k² (100, 400, 900, 1600, 2500...). Win early and every turn you have left is worth +1,000.

Features

• 30-second tutorial puzzles that teach the chain trick
• Chain preview while dragging
• Daily Seed — everyone gets the same board each day
• Rising bloom notes as the chain grows

Controls

Mouse or touch. Drag & drop, or tap-to-select then tap a tile. Best in portrait / fullscreen.
