DNA Splice: Sequence Quest

DNA Splice — Sequence Quest
A gentle, brain-building puzzle adventure! Help four squishy DNA monster friends — Adenine (A), Thymine (T), Cytosine (C), and Guanine (G) — find their perfect pairs across 30 hand-crafted levels. Tap two neighbors to swap them, watch the green checkmarks pop in, and earn star ratings as you climb from beginner to genetic genius!

Learn Without Realizing It
Behind the cuddly monsters is real science:

A always pairs with T
C always pairs with G
By the end of level 5, you'll have internalized DNA base-pairing — the foundation of genetics — without ever opening a textbook.

30 Hand-Crafted Levels
Every puzzle is mathematically guaranteed solvable. No frustrating dead-ends. Difficulty ramps gently:

Levels 1-3 — Tiny 4-base strands, 1-2 swaps to win
Levels 4-10 — 5-6 monsters, gradual challenge
Levels 11-22 — 7-8 base puzzles
Levels 23-30 — 9-monster master strands
Gorgeous 2.5D Monster Art
Every base is a cuddly volume-shaded creature with personality:

Blue Adenine — one big shiny eye and tiny horns
Orange Thymine — two friendly eyes, ears, and a grin
Green Cytosine — three pyramid eyes and curious "O" mouth
Pink Guanine — four eyes and a chunky square body
Relaxing Sound Design
