The idea is to use coin fliping instead of a dice role.

their are two ways to play this;

**Simplest way**

You need:

A coin.

Lego.

Its VERY simple really.

Heads=success

Tails=fail

then flip again

Heads=critical

Tails=non-crit

This system means their would be more critical success and critical fails so the game should go faster. (which is ideal for a "travel" version)

**slightly less simple system one:**

You need:

As many coins as the number of sides on the dice needed for that roll.

Simple maths skills.

LEGO!!!!!

Flip the number of coins equal to the number of sides of the dice normally used (if 2 dice are used then flip coins for both), count the number that landed on "heads" that is the roll score.
