The Velleman Dual Electronic Dice Kit board game provides an excellent source of pleasant and healthy entertainment. However, the dice can be a constant source of distraction : they fall off the table, allow cheating, one or more players don't see the results properly and so on. There can be no doubt at all about the result displayed on this electronic dice module, and cheating is out of the question. Two fully independent dice. At your choice you can play with one or two dice. With the K3400 kit displays are switched off automatically after 30 seconds to save battery power.
