How It Stacks

Racks, storage troughs, lid, and box stay together

The four player trays nest into the storage box with the storage troughs and lid, keeping loose tiles contained between games.

Load trays

Four player racks stack into the box as a matched set.

Set storage troughs

Integrated storage trough pieces help keep loose tiles organized inside the box.

Close the lid

The lidded box protects the system between sessions.

Reset fast

Open the box and stage the trays with fewer loose parts.
