Riddles, dice games, pencil-and-paper battles and challenges to beat your own record. No screen, no downloads, no waiting.

Losing is allowed. Arguing about the rules is allowed, briefly. Flipping the board is not.
Read the riddle, think as long as you like, then tap to see the answer. No peeking early. The best ones are the ones you nearly had.

Fold the dart, throw it, measure it, write it down. Then change one thing and throw again. By the end you'll have a plane that goes twice as far as your first one and a chart to prove it.
Build the tallest house of cards you can before it falls. Sounds simple. Ask anyone who's tried three storeys.
One person thinks of a thing. Everyone else gets twenty yes-or-no questions to work out what it is. Perfect for car rides, waiting rooms and the last ten minutes before bed.
Start with three dots. Take turns joining dots with a line and adding a new dot on it. Lines can't cross and a dot can only have three lines. The first player who can't move loses. Simple rules, sneaky game.
