How it works

Each card holds a shape, a color, and a word. The word often lies. Count, locate, or name an attribute, then type the answer and press Enter. Prefixes count: tri is triangle, vio is purple. You can also tap a chip.

In Flash, the field is taken away. In Drift, it grows and the clock tightens. Daily uses today’s date as a seed, so everyone sees the same twenty.
