Crazy eights forces rapid ideation by limiting you to one minute per sketch. Eight frames, eight different ideas, no time to fall in love with any one of them. The best ideas come after the obvious ones run out.
Run crazy eights during the sketching phase of a design sprint, at the start of any ideation session where fixation is a risk, or when a team keeps circling back to the same solution and needs to break the pattern.
The one-minute constraint is the method. It's fast enough to prevent overthinking and slow enough to force a real sketch. Don't reduce it, the time pressure is what produces unexpected ideas.
The first two sketches are almost always the obvious ideas, the ones everyone in the room would draw if they had unlimited time. That's fine. Get the obvious ideas out in the first two minutes so you can move past them. Think of frames 1 to 2 as clearing the mental cache.
By frame three, the obvious ideas are exhausted and the sketches start to vary. This is where alternative approaches to the same problem emerge. The constraint forces exploration, you don't have time to go back to the obvious ideas, so you have to try something different.
The most valuable frames. At this point, the obvious approaches are spent and the mind starts combining elements from different frames, borrowing from analogous domains, or simplifying radically. The unexpected ideas that appear in frames 5 to 7 are what crazy eights is designed to produce.
The hardest frames. You've run out of easy ideas and you still have two minutes left. Push for something genuinely different, a completely different interaction model, a different user entry point, a solution that removes the problem rather than solving it. The push frames often produce the most creative output.
Fold a blank piece of paper in half three times to create eight equal sections. Unfold. Write a number in each section: 1 to 8. Every participant needs their own sheet. If doing this on a whiteboard, divide a section into eight frames.
Write the design challenge at the top of the board: 'How do we make it easy to capture whiteboard action items in under 30 seconds?' Everyone is sketching solutions to the same challenge. Specificity matters, a vague challenge produces vague sketches.
One minute per frame. Call 'next' at the end of each minute. No talking. No phone-checking. No erasing. If a sketch is going poorly, move on, you don't have time to fix it. The discipline is moving, not perfecting.
Post all eight sheets on the wall at the same time. Don't present them yet, just look. The visual density of all the sketches side by side reveals patterns and combinations that weren't visible when each was drawn in isolation.
Each participant gets 8 small dot stickers. Put a dot on each sketch (across everyone's sheets) that has an interesting idea, could be a specific element, not the whole sketch. The dots show where the most interesting ideas cluster.
Snap the posted sheets with BoardSnap before the discussion phase. The AI reads each frame and outputs a visual inventory of the idea space, useful for the speed critique step that follows.
A room of eight crazy-eights sheets is visually dense, eighty total frames from a ten-person session, each containing a rough sketch that needs to be preserved for the speed critique and voting phases. Photographing that material is important; photographing it well enough to be legible and useful is hard.
BoardSnap's VisionKit perspective correction flattens and sharpens each sheet. The AI reads the sketches and outputs a structured inventory of the idea elements, which interactions appeared, which patterns repeated across participants, which frames drew the most votes. The session's creative output becomes a navigable artifact rather than a pile of paper.
No, and that's the point. Rough boxes and arrows are sufficient. The goal is to get ideas out of your head and onto paper fast enough to generate eight genuinely different concepts. Polished sketches in a crazy eights session usually indicate someone is spending 45 seconds on one frame and racing through the rest.
Push them to keep going. The discomfort of frames 6 to 8 is the point, the ideas that come after you think you've run out are often the most interesting ones. Common prompts for stuck participants: 'What if you removed a step?' 'What if you approached it from the opposite direction?' 'What if the solution was invisible?'
Yes, it's a powerful individual ideation exercise. Set a timer, set a design challenge, and run through eight frames alone. Individual crazy eights produces different results than group crazy eights: without the social pressure, people often explore weirder ideas in frames 5 to 8.
In a design sprint: a 3-minute review of each participant's eight frames, heat map voting on interesting elements, and then a more detailed solution sketch (20 minutes) that elaborates on the most promising concept. Outside a design sprint: the sketches feed into a group discussion or affinity clustering of the ideas that emerged.
