**GAME PRINCIPLES**

**"****Exploring arithmetic & math through play ****".**

## LEGENDA

**The game consists of one large triangle that is divided into two smaller triangles and a quadrangle. Inside these three figures – i.e. the fields – are the CELL values or target numbers. In this puzzle there are 3 CELL values.**

**The fields or cells are surrounded by nodes. There are 6 nodes in total. Additionally, players are given (6) play values. The play values must be placed in the nodes in such a way that the SUM (addition +) or PRODUCT (multiplication X) of the surrounding node values equals the required field value. **** **

** **

**The concept is simple, but the solution requires quite a bit of brainpower. **

### It is a combination of analyzing, reasoning and trying out.

**RESOLF will provide the puzzles, but you must work out the solutions! **

### Each puzzle has a unique solution and, naturally, the answer key is included.

### Off course there is HELP like HINTS or some PLAY values are equal.

**The animation on the right shows a step-by-step explanation of how to play the game.**

**In this math puzzle, the addition (+) or sum of the play values must equal the value in each field. **

**In fact, the purpose is to determine the correct order, arrangement of the play values leading to the required field values. **

**Footnote: another (mathematical) word for arrangement is permutation. **
