The Euchre cube, designed by Patrick O’Donnell and self-published, differs from your typical Euchre scoring pads and peg tracks in that it prominently indicates the dealer (the guy next to the cube) and trump. The inside has a recessed Euchre scoring track.

It’s patented, includes a bag to hold the cube (a deck of cards will also fit in there), and costs $45 (plus shipping).
