Bounce Tips: Paddle Angles, Speed Steps and Staying Centred

Updated October 2026

Bounce looks like the simplest game on the site: one ball, one paddle, three walls. Yet most runs end in the twenties, just as the ball starts to feel fast. The reason is rarely slow reflexes. It is usually that the player has been reacting to the ball instead of steering it. This guide explains how the return angle is calculated, how quickly the ball accelerates (it never stops), and the positional habits that keep a run going as long as your reactions can.

What the paddle actually does

The paddle sits a little above the bottom of the play area and only moves sideways. When you put a finger on the play area, the paddle does not slide toward it gradually: its centre jumps straight to the horizontal position of your finger, and from then on it follows your finger as you drag. Lifting your finger leaves it where it is. At the start of every run the ball hangs in place until your first touch, so a run never starts before you are ready. On a keyboard, each press of the left or right arrow shifts it by 28 pixels.

The paddle is 22 percent of the play-area width, but never narrower than 70 pixels or wider than 120. On a typical 390-pixel-wide phone that works out to roughly 79 pixels. A catch is generous at the sides: the ball counts as caught if any part of it overlaps the paddle, so the ball's centre can be up to its own radius (8 pixels) beyond either end and still be returned. Only a ball moving downward can be caught, so you never get a false catch from a ball that has just left the paddle.

Because the paddle teleports to your touch, the cleanest control style is to keep one finger resting on the screen for the whole run and drag. Repeatedly lifting and re-tapping works, but every new touch snaps the paddle to wherever that finger lands, which is a common source of sudden misses.

The angle rule: you aim with the paddle, not the wall

The return direction depends only on where the ball meets the paddle. The game measures the distance between the ball's centre and the paddle's centre, divides it by half the paddle width, and turns that into an angle between 6 and 60 degrees from vertical. A dead-centre catch sends the ball almost straight up, leaning about 6 degrees to one side. A catch halfway out sends it off at about 33 degrees. A catch at the very end, or on the overhang just past it, sends it out at the full 60 degrees toward that side.

Two details matter here. First, the incoming direction is ignored completely. A ball that arrives from the far left at a steep slant and lands on the centre still leaves at the same steep 6 degrees. That means every catch is a fresh start, and you can always calm a messy rally with one centred hit. Second, the side walls and the ceiling reflect the ball perfectly with no loss of speed, so the path after a catch is completely predictable. If you know the angle you sent it at, you know where it will come down.

How fast the ball gets

The first ball drops from a quarter of the way down the screen, starting from the middle, aimed within about 22 degrees of straight down, at 240 pixels per second on a 390 by 844 screen. The speed is set as a share of the play-area height, so a smaller screen moves the ball fewer pixels per second and every rally takes the same time on any phone. Each successful catch adds one point and multiplies the speed by 1.04. The increase compounds, so it is gentle at first and then noticeable:

• After 10 catches the ball moves at roughly 355 pixels per second (figures for the same 390 by 844 screen).
• After 20 catches it is around 525.
• After 30 catches it is around 780.
• After 34 catches it passes 900, after 40 it is around 1,150, after 50 around 1,700 and after 60 around 2,500.

There is no top speed. Every catch makes the next one about 4 percent harder, so a run always ends; the question is only how far your reactions carry you. Surviving a rally at a given speed proves nothing about the next one, because the next one is faster.

To put the speed in context, by our calculation on a 390 by 844 screen the ball has about 618 pixels of vertical travel between the paddle and the ceiling. A steep centre return at 900 pixels per second comes back in roughly 1.4 seconds; at the 50th catch it takes about 0.7 seconds and at the 60th about half a second. From about the 37th catch the ball crosses the whole width of the box in under 0.35 seconds, and from about the 51st it falls from the ceiling to the paddle in under 0.35 seconds. A shot sent at the full 60 degrees takes about twice as long as a centre return, because only half of its speed is vertical, but it crosses the screen several times on the way, bouncing off the side walls.

Choosing your return: time versus predictability

The angle rule gives you a real choice on every catch, and good players make it deliberately.

• Centre hits are the safest return. The ball goes nearly straight up and comes down a predictable distance to the side: on a 390-pixel-wide phone about 130 pixels from where it left, more than a paddle width, toward the side of the paddle it touched. You always need one small move, but you know where to. The cost is that the round trip is as short as it can be.
• Moderate offsets buy time. A hit a quarter or a third of the way out from centre adds some sideways travel and a little extra flight time, while staying easy to read. The ball will usually reach one side wall and come back toward the middle.
• Edge hits buy the most time but the least certainty. At 60 degrees the vertical speed halves, so you get the longest wait, but the ball zigzags between the walls and the landing point is harder to judge, especially at high speed.

A practical rule is to use centre hits whenever the ball is fast and you feel rushed, and moderate angles when you want a breath. Edge catches are for emergencies: if you only just reach the ball with the tip of the paddle, accept the steep return and immediately move back toward the middle to meet it.

Positioning: drift home after every catch

Most deaths at speed happen because the paddle was left near a wall after a stretch catch. From there, a ball that comes down on the opposite side is simply out of reach. After every catch, while the ball is climbing, slide the paddle back toward the centre. A centred paddle covers both halves of the screen; a cornered paddle covers one.

Next, learn to read the landing point early. Because the walls are perfect mirrors, you can treat the sideways motion as if the ball keeps travelling through the wall into a mirrored copy of the screen. In practice this means watching the ball at the top of its flight, deciding which side it will come down on, and starting to move there before it has dropped halfway. Late, frantic movement is what produces near-misses with the paddle tip, and those produce the steep returns that are hardest to follow up.

Finally, mind the overhang. Since a ball whose centre is just past the paddle end still counts, you have a few extra pixels at each side. Do not rely on them, but do not give up on a ball that seems a fraction too wide either.

Common mistakes

• Chasing with the finger lifted. Re-tapping snaps the paddle to the new touch point. If your tap lands off target, the paddle teleports away from the ball.
• Over-correcting at the last moment. A small late nudge changes the return angle a lot. Arrive early and hold still, so you choose the angle instead of stumbling into it.
• Treating every hit the same. The angle rule is the whole game. If you are not deciding where on the paddle to take the ball, you are leaving the outcome to chance.
• Panicking near 30 points. This is where the speed starts to feel like it is running away, and it keeps climbing. Panic makes it worse: hold your technique, keep the finger down and keep choosing the angle on every catch.

A short practice routine

1. Play a few slow early rallies taking every catch on the centre of the paddle, so you see how cleanly a straight return comes back.
2. Then alternate deliberately: one catch at the centre, one a third of the way out to the left, one to the right. Watch where each angle lands.
3. Practise the drift home: after each catch, say "centre" to yourself and move there before the ball reaches the top.
4. Finally, push past your best one catch at a time. Each new record is a rally faster than any you have survived, so the steady habits above matter more the longer the run lasts.

Your best score is kept on your device, and the game-over card lets you send a result to the Hall of Fame. Learn to aim with the paddle, keep it near the middle, and see how far your reactions can take the speed.
