24 Game MultiplyDivide Jumping Levels 4 to 7

This deck contains cards of two types. One type has on each side a circle divided into four quadrants, with a single-digit number in each of these quadrants. By a series of simple operations, the digits in each circle can be combined to produce the number 24. The second type of card has, on one side, two circles divided into four quadrants. On each of the easy cards, two quadrants have a single digit. On each of the medium and difficult cards, three quadrants have a digit. A number is printed in the margin. Players are to determine a series of operations on all the digits in the quadrants of one circle that will yield the number in the margin. The reverse of each of these cards has printed on it two numbers with a common factor. All cards of this type are marked “ADVANTA”.
The deck has 15 easy cards, each marked with a single dot; 16 medium cards, which have two dots; 16 difficult cards, which have three dots; and a cover card. The goal of the game apparently is to choose a set of cards of given level of difficulty and quickly solve the problem on it. Once a student could accomplish this correctly within certain time limits, he or she “jumped” to another level and received an award.
A mark on the cover card reads: 24 (/) GAME (/) MULTIPLY/DIVIDE (/) JUMPING LEVELS TM 4 to 7. Another mark there readsL SUNTEX (/) INTERNATIONAL INC. A third maker’s mark reads: [copyright sign] 1995. A paper tag on the cover card reads: Benjy.
According to Robert Sun, the designer of the 24 Game, these are “mini-cards,” interim take-home cards that were distributed 24 to a pack. This may represent two packs, but they are not duplicates.
The example was obtained by the donor at Georgetown Day School in the period 1996–1999.
