Color Clash

Color Clash is a Stroop-style speed round. A colour word flashes up on each player's phone, printed in an ink colour that may or may not match what it says (the word "RED" might be printed in blue). Players tap Match or No match as fast as they can, and the sharpest, quickest players climb the leaderboard. It's a great quick mental jolt with nothing to read out and no questions to write.

How players experience it

1. A synced 3-2-1 countdown leads everyone in, so every phone starts at the same moment.
2. A colour word appears in a coloured ink. The player decides: does the ink match what the word says? They tap Match or No match.
3. As soon as they answer, the next prompt appears, so it's tap, tap, tap for the whole round. Each correct call earns a point and each wrong call costs one; a player's score never drops below zero.
4. Their score streams live to the big screen, so the presenter's leaderboard climbs in real time as people play.
5. When the round window runs out, each phone locks in its final score and everyone looks up to the big screen for the ranking.

The prompts are generated on each player's phone, so no two people see exactly the same sequence. It's all about accuracy under time pressure.

Setting one up as a host

Color Clash is one of the simplest activities to add. There's nothing to write.

• The only thing you choose is the round window: how long the round lasts. Pick from 20, 30, 45, or 60 seconds (it defaults to 30).
• That's it. The colour prompts are generated automatically on each player's device, so there are no questions, answers, or content to prepare.

Tips

• Drop it in as an energiser. Because there's nothing to set up, Color Clash is perfect for breaking up heavier activities like quizzes or polls.
• Keep the window short. 20 or 30 seconds keeps the pressure high and the energy up. The whole point is a fast mental burst.
• Play it on the big screen. The live leaderboard and the ticking timer make it a fun spectator moment, so put the presenter view up where everyone can see it.
