Diamond Rush remains one of the most iconic puzzle-platformer games from the golden era of Java mobile gaming (J2ME). If you are searching for the "Diamond Rush jar 320x240 new" version, you are likely looking to relive the adventure on a legacy Nokia, Samsung, or Sony Ericsson device, or through an emulator on your Android smartphone.
