Eight ideas.
Eight minutes. Go.

One minute a frame, enforced: The timebox is the mechanism, not an inconvenience. Loosen it and people produce four polished versions of one concept instead of eight different attempts, which defeats the entire exercise.

Quantity over quality, said out loud: State at the start that nobody is judging the drawing. Rooms that are not told this spend the first three frames worrying about how their sketches look and lose half the round.

Frames five to eight are the point: The first few frames are the ideas everyone already had. The value of the exercise is that it forces you past them, which is why stopping at four is not a shorter version of Crazy 8s, it is a different and worse exercise.

Silent review before any discussion: Let people read every sheet with no narration. An idea that needs its author standing beside it is an idea that will need a salesperson standing beside the product.

Prompt against the whole canvas: Ask it to lay out grids for six people, sharpen the framing question, or propose provocations for a second round when the first one produced eight versions of the same idea.

Use it to widen, not to answer: Hand a room an AI-generated solution and the sketching stops immediately. Angles and constraints keep people generating; conclusions end the exercise before it starts.

Iterate without losing work: Re-prompt as often as you want. Sketches people have already drawn stay exactly where they are while the AI builds around them.

Everyone sketches in parallel: Each participant works in their own area of the canvas at the same time. Nobody waits for a turn and nobody has to hold a piece of paper up to a laptop camera.

No photographing, no transcribing: When the timer stops the sheets are already digital and already side by side, which removes the most tedious ten minutes of a paper-based sprint.

Hybrid without a second-class half: When the board is the exercise rather than a camera pointed at a wall, remote participants contribute on exactly the same terms as the people in the room.

Solution sketch from the winner: In a full sprint the voted frame becomes a three-panel solution sketch. Build it in the next region of the same canvas so the lineage from rough frame to concept stays visible.

Wireframe or storyboard it: Take the direction into a wireframe or a storyboard on the same board, with the original sketch beside it, so nobody loses the reason the idea was chosen.

Share the reasoning: Send a view-only link with every sheet and the votes visible. People who missed the session can see what was considered, which stops the decision being relitigated in a week.
