Daily puzzles

Tilt Tilt the tray and roll every marble into its hole. Two puzzles a day: a warm-up, then the real one.

Balance Hang every weight on a peg so the beam lies level, with no wasted move. Two beams a day.

Calendar Cover every square except today's month, day and weekday.

Tangram Fill today's silhouette with the seven classic pieces. Fifteen figures, one a day.

Sudoku One puzzle a day, the same for everyone. Gentle on Monday, hardest on Sunday.

Nonogram Read the numbers, fill the squares, and a picture appears. One 10×10 picture a day, Monday gentle, the weekend hardest.

Echo Ping the dark pool, read the echoes and find the hidden stones in as few pings as you can. Two pools a day.
