nine

nine is a minimalist slide puzzle where you push a number tile through a grid of math operators to reach the star ★
safely.

▶ How to play
Swipe to slide your tile — it moves until it hits a wall.
Every operator cell in your path changes your number (+, −, ×, ÷).
Gates only let you through if your number meets the condition.
Reach the star ★ with the right number to clear the stage!

▶ Cell types
• Operator cells — add, subtract, multiply, or divide your number as you pass through
• Gate cells — only passable when your number satisfies the condition (>, <, =)
• Stop cells — bring your tile to a halt on the spot
• Walls — boundaries that shape and restrict your path
