What is "JezzBall Classic"?

JezzBall Classic is a game where you shall contain two or more bouncing atoms in as little space as you can. This is accomplished by building walls, when over 75% of the play area has been built upon the current level is won and the game advances by adding another atom into play. Each level you have the same amount of lives as the number of atoms in play, when an atom crashes into a pending wall a life is lost and the game is over when all lives are spent.

The game is a version of the 25 years old "JezzBall". It is created to be as close to the original as possible in as many ways as possible. However JezzBall Classic also adds to the original by supplying optional mods that drastically changes how you play the game in order to offer more variation.

Out now on PC, Android and iOS!

There's a lite version available so that
you can try the game for free!


Note 1: In-game frame rate is 60 FPS. This is not reflected in the video due to some limitations in the recording software, plus the fact that the video is only 24 FPS. Because of this the atoms may appear to not move smoothly. Please be aware that this is not the case when you actually play the game, in reality the atoms do in fact move smoothly at 60 FPS.

Note 2: The game is mute, it has neither sound effects nor music. That is why "Canon in D Major" is being played in the video.

Note 3: This video is now many years old and is not representative of the improved quality of version 2.0.0 (the PC release).

If you watch in fullscreen you might want
to change to HD resolution.

A bunch of new things has been added to the game that aren't shown in the video above, for example the following three presets:

The war - Dodge missiles and use the General atom to teleport troops (atoms) into smaller cells.

The inferno - Lava has gotten into the capture chamber, find the best way to build between the puddles.

The haste spell - Everything moves twice as fast as usual, can you keep up?

The appender - Every level has a pre-built wall piece in it to aid you but in turn two new atoms are added into the chamber instead of one.

The bear cave - You're stuck in a cave filled with angry bears! The only way out is to trap them.

The caretakers - One atom moves twice as fast as the others.


Note: These screenshots are not representative of the quality of the game today, look on for new screenshots from 2.0.0!


+ The original JezzBall experience! Into the very last detail; if you came looking for the JezzBall you remember you will not be disappointed!

+ Four profiles (one reserved for guests) with their configurations stored separately.

+ 700 beautiful background images (real life photos). Go to the "Graphics" config screen to enable it. Will place a random image into the black walls each level.

+ 8 music tracks of classic MIDI tunes you'll probably remember! All recorded using SoundBlaster 16. You can set up to 24 music audio events if you want to.

+ 60 fully customizable SFX audio events - change which sample(s) to play or change individual volumes. A pool of 300 sounds are available from various old games.

+ Automatic saving of all games in progress. Stop and continue whenever you want to!

+ Local high score lists. In the Hall of Fame your name will last forever and on the three other lists you will see the daily, weekly and monthly high scores.

+ Level records. All your best statistics are saved on each and every level you complete. Profile records are comparable.

+ Smart and very customizable controls. If you have a touchscreen you can play using your fingers.

+ 83 mods that once activated changes how the game is played! Use none or pick one/several at the same time in any order. High scores and level records are stored separately for each combination. Some mods will just change the amount of time/lives you have while other will drastically change gameplay (allow you to use two wallbuilders at the same time for example).

+ 22 preset mod-combinations are provided in addition to the original JezzBall experience to give you variation.

+ 100 rooms that will stimulate your intellect as well as your ability to time your deployments! Can you solve them?

+ There are also missions available to inspire you to break your personal bests. Completing them all is an achievement!

Sales pitch

25 years ago people could first play the original JezzBall. Since then a lot of different versions of it has been created, and although some have been great none of them were really close to the original.

JezzBall Classic changes that; it was created to be just like the original! The graphics, the scoring, the physics, the tempo... they are all the same as they were in the original.

The animations has been given a lot more frames to suit today's standards and many new optional features has been implemented. Some bugs and issues of the original has also been solved, for example expert players will be happy to know that the game will now end after 50 levels instead of repeating level 49 over and over again forever. Measurements have been taken to prevent cheating by pausing the game or switching between slow/fast speed right before the last move.

But the true JezzBall feeling can still be found in this JezzBall Classic, and that's what really is important!

How you play on your touch device:

Press down to place the origin of the wall, move your finger to determine the orientation of the wall and release it to actually start building the wall. It is constructed in two directions from the center, if a wall-half is hit by a Jezz atom before it has reached an already existing black wall it is destroyed and you lose a life.


The game is available for PC, Android and iOS.

There is a free lite version out and a full one that costs less than a cinema ticket (not even counting the popcorn and soda), but I promise you will get more hours out of JezzBall than a movie!
