Trek 12 is a roll-and-write alpinism game, with progressive difficulty levels and more. To score points, you have to create chains of consecutive numbers from 0 to 12 and areas of a same number.

A game is composed of 19 rolls of two six-sided dice, with one die having values from 1 to 6, and the other from 0 to 5. After each roll, the player must combine both die values to obtain the number to place. You can:

Add the values of the two dice
Subtract the value of one die from the other
Multiply the value of the two dice
Keep the higher value of the two dice
Keep the lower value of the two dice

Be careful as you may choose each of these options at most four times during a game. After placing your first number on the game sheet, you must place each subsequent number in a space adjacent to one already filled. You try to make chains and develop areas. Players also have access to several bonus elements to earn during a game.

At the end of a game, numbers that belong to neither a chain nor an area give you minus points. The same applies if you have to place a number greater than 12...

Trek 12 contains three different sheet pads to add narrative with three progressive difficulty levels.
