The game

Bounceplot is a free daily physics puzzle. Predict where a bouncing ball lands: no gravity, straight lines between bounces, and angle in equals angle out. Everyone gets the same three levels each day, and Endurance mode is there when one puzzle is not enough.

How to play

Read the board. The launch arrow shows the direction; the bounce count says how many times the ball bounces before it lands.
Pick a zone. Pick one of four landing zones (A–D) and tap Lock it in.
Three reads per level. A wrong read knocks out that zone and reveals the true path, one bounce at a time. A correct read, or the third, launches the ball.

Scoring

★★★ solved on the first read
★★ second read
★ third read
No stars out of reads

Plotting with the sketch kit is free. The three levels, each with more bounces than the last (two or three, then three or four, then four or five), add up to a day score out of 9. Finish all three to keep your day streak, and "Top N% today" shows how your score ranks among today's players once five have finished.

Endurance mode

An endless run. Round one has one bounce, every round adds another (up to 5), and one miss ends the run. Every round is a fresh board, generated on your device.
