1 x playing unit;
- 1 mechanical timer
- 20 holes in centre piece
- 20 peg holders in base section
20 x pegs numbered 1 to 20
1 x instructions

Complete a number sequence against the clock. Set the board by inserting 20 pegs in the centre section of the unit. The race is on to lift out one peg at a time. Your sequence must start with number 1, so remember (any) failed attempts and once you’ve found it, you (might) know where the next number is! Move each number peg in order to the bottom of the unit, until the timer runs out. Your score is the sum of the pegs found.

Simple but great fun.
