About this game
FibDefense is a tower defense game with one rule that changes everything: a tower can only fire when its shot reduces a monster's health to exactly zero. No overkill, ever.
Every tower deals a Fibonacci value — 1, 2, 3, 5, 8, 13, 21, or 34. To destroy a monster you combine the right towers so their damage sums precisely to its remaining HP. Thanks to a mathematical principle called Zeckendorf's theorem, every monster has at least one valid solution — but finding it under pressure, as the waves close in, is where the strategy lives.
WHY IT'S DIFFERENT
Most tower defense games reward raw power. FibDefense rewards precision. Placement, timing, and number sense matter more than brute force. When your towers chain together and drop a monster in a perfect cascade to zero, it feels like solving a puzzle and winning a battle at the same time.
WHAT'S INSIDE
- Six themed worlds — Fantasy, Sci-Fi, Military, Retro, Pirates, and Horror — each with its own art and atmosphere
- Multiple modes, including a 20-wave Campaign, Continuous, and Endless Waves
- Four difficulty levels that raise the challenge by making the Fibonacci combinations harder to assemble — not just by inflating numbers
- Boss encounters that test everything you've learned
- Speed controls so you can play at your own pace
BUILT TO RESPECT YOU
- Plays fully offline
- No account or sign-up required
- A single one-time unlock opens all worlds, harder difficulties, and extra modes — no subscriptions
Whether you love tower defense, enjoy number puzzles, or just want a strategy game that makes you think, FibDefense is a fresh challenge built on real mathematics.
