Phi Zen Fibonacci Merge Puzzle

Simple rules, brutal physics. Drop, merge, and try to reach 144 before your container fills up.

Drop, match, and merge your way through the Fibonacci sequence in this physics-based puzzle game.

The rules are simple: drop balls into the container. When two balls with the same number touch, they merge into the next Fibonacci number. 1+1 becomes 2, 2+2 becomes 3, 3+3 becomes 5, and so on. Your goal? Reach 144.

It sounds easy. It isn't. Every drop matters. The container fills up fast, and one careless move can end your run. Line up chain merges to rack up combo multipliers, or watch your balls pile up past the line.
