Two Truths and a Lie
Each player states three claims; the rest must reason out which is false from tone, detail, and plausibility. Trains evidence-weighing.
20 Questions
Narrow an unknown with yes/no questions. Good players prune the space efficiently — pure hypothesis-testing.
Spot the Assumption
Read a short ad or headline aloud; players race to name the hidden assumption it relies on.
Logic grid puzzles
Printable grids where clues eliminate possibilities until one solution remains. Great solo warm-up.
Fallacy hunt
Give everyone the same opinion piece; first to correctly name a logical fallacy with a reason wins the round.
What happens next?
Pause a story or video; players predict the outcome and justify it from the clues so far.

Hidden roles and bluffing: work out who is lying from limited, sometimes deceptive information.
Games for kids
For children, choose games where they must explain why, not just guess: 20 Questions, cooperative deduction, and logic puzzles all work. Keep rounds short and ask "how did you figure that out?" after each one.
Do games really improve critical thinking?
They help most when you reflect afterwards. A game that forces genuine choices, followed by a quick "what was my reasoning?", beats passive play. Combine games with the exercises and activities, then retake the test to see your progress.
