How do I play Portal Bounce?

Watch the ball's launch direction shown by the arrow. Tap two empty cells to place a pair of warp portals — orange and blue. When the ball enters one portal it teleports to the other, keeping its direction. Tap Launch to send the ball bouncing. Collect all stars and reach the green exit to win.

How does the ball bounce?

The ball moves diagonally and bounces off walls like a billiard ball. When it hits a vertical wall it reflects horizontally; when it hits a horizontal wall it reflects vertically. The path is fully deterministic — the puzzle is figuring out where to place portals to redirect the ball to stars and the exit.

What are the stars for?

You must collect every star on a level before reaching the exit. If the ball reaches the exit without all stars, it passes through. Plan your portal placement so the ball collects stars first, then hits the exit.

How many levels are there?

There are 30 handcrafted levels across 6 tiers of increasing difficulty, from basic portal redirects to complex puzzles with spikes, internal walls, and precision placement.
