Chain Relations is a small casual existential game about life, human needs and long-term relations.

Game objective: connect the balls' same-colored inputs to outputs. Completely connected balls disappear. The possible connection range is limited, so plan your moves.

You can adjust balls count, connection range, whether the balls are respawned, and put additional color to the board.

Hint: from time to time balls blink and randomly change their colors one by one, so if you are out of the moves, you can just wait a bit.

The game is intended to be meditative, so there is no game timer and no hall of fame. There are also no sound, no ads and no in-game purchases. The game is completely free and will remain so. It does not use Internet connection and does not require any device permissions.

The game is auto-saved every 5 seconds, so if you close it immediately after a move, you might lose up to last 5 seconds of the game.

The game is provided in two options:

• Desktop Java. Download ChainRelations.jar. Run it with java -jar ChainRelations.jar command line, or in most cases just double-click the ChainRelations.jar file. It has been tested with Java 18 Runtime, should also work with prior versions up to Java 8.

  • On MacOS you will get a warning about unidentified developer. Start the ChainRelations.jar using Finder context menu instead of Launchpad, as explained here .

• Android. Get it on Google Play (recommended) or download the ChainRelations.apk here for manual install (it might be sometimes also a newer version than on the Google Play). It has been tested on Android 8.0 and 10.0, should also work on any Android version starting from 4.4 and later.

There is no iOS build because I do not have tools to test and deploy it to the AppStore. If somebody completes the iOS module (see below), I will add it here.
