Abstract
Abstract A holder for setting a group of tiles on a receiving surface has a base plate provided with permanent magnets dispersed over its surface to hold an array of magnetically attractable tiles. Pusher pins slide through the plate to push tiles therefrom. In an alternate form the plate is made of or incorporates magnetically attractable material for holding tiles having permanent magnets therein.
