Crazy 8s Wall
Crazy 8s Wall runs the Crazy 8s sketching exercise online: eight cards, eight minutes, one idea per card. It pushes a team toward many ideas fast, rather than one polished one.
Use Crazy 8s Wall together on your board.
Everyone sketches on their own sheet in silence while the clock runs. When the timer hits zero every card locks and the whole wall is revealed together for critique.
It runs on a shared MockFlow board, so the prompt, the timer and the reveal are the same for everyone.
- Eight card sheet. Each person gets eight cards to fill, one idea per card.
- Drawing on each card. Sketch freehand straight onto a card.
- Shared timer. One countdown for the whole board keeps everyone on pace.
- Lock and reveal. Cards lock at zero and the wall opens for everyone at once.
- Clear the wall. Wipe every sheet and the timer in one step for a fresh round.
- Your own prompt. Update content with AI changes the prompt and rules to fit your problem.
