To play with two teams, print each clue, the planning sheet and other documents for the children (worksheet, codes, magic formulae, challenge cards, etc.) twice. Put a mark on the sheets to enable you to differentiate the documents for the two teams. You may also wish to give a name to each team relating to the theme of the game.
To stop the two teams looking for the same hiding places at the same time, you need to stagger the starting points (see table: C1 = Clue 1; TA = Team A; HP1 = Hiding Place 1). The first box B1 (in red) means that clue 1 for team A (TA) will be hidden in hiding place 1 of your planning sheet. Box B5 (in purple) means that clue 1 for team B (TB) will be hidden in hiding place 5 of your sheet, etc.
In two-team configuration, make a note on your planning sheet of the points won by each team. Clues solved successfully win 10 points. 5 points are deducted for an incorrect answer. In case of a draw at the end of the game, the first team to finish the adventure wins the game.
For children under 8 years of age, we recommend playing in a single team.
