Brought new life to my Scramble cabinet
I was originally looking for a way to keep my Scramble machine interesting without losing the original hardware, and this multigame kit was exactly what I wanted. The extra games give everyone something different to play, and changing between them is quick and simple.
Installation went smoothly, the instructions were well written, and the kit worked perfectly from the first boot. Everything fits cleanly with no permanent changes to the PCB, which was important to me as a collector. The quality of the kit is excellent, shipping was fast, and it was packaged with care.
It's rare to find an upgrade that adds so much value while still respecting the originality of the cabinet. If you're on the fence about the Scramble Multigame Kit, I'd buy it again without hesitation.
