Reading through the first couple chapters of the Monte Cook's Cypher System, and it is pretty neat. The only thing that seems a bit odd to me is the requirement to multiply a Difficulty rating (1-10) to a Target Number rating (Difficulty x3) which is actually rolled against. This seems especially odd in the case of expending effort, where you spend several points to lower the difficulty, which in turn lowers the Target Number, which you then roll against.

Also while reading, the three pool system brought to mind Michael Wolf's wonderful WYRM System. This in turn led to wondering:

Why not just roll a d6 for Cypher and cut out the x3 Difficulty conversion?

Looking into this, there's little trouble so far in switching from d20 to a d6 system.

Maybe as I read Cypher further there'll be a later section where the need to multiply by x3 will be better justified. But in the meantime, the conversion seems pretty straightforward:

**Basic
roll**

**Basic roll**

The
standard roll for each system is as follows:

Cypher: |
Roll
1d20
TN
(3-30) = 3x Difficulty (1-10) |

d6: |
Roll
1d6 TN (1-10) = Difficulty (1-10) |

**Special Rolls**Conversion:

Cypher: |
Roll
17 = +1 Damage Roll 18 = +2 Damage Roll 19 = +3 Damage or Minor effect Roll 20 = +4 Damage or Major effect |

d6: |
If
rolling a 6, reroll and interpret the reroll as follows: Reroll 1 = +1 Damage Reroll 2 = +2 Damage Reroll 3-4 = +3 Damage or Minor effect Reroll 5-6 = +4 Damage or Major effect |

##
**Effort**

**Effort**

*Example: Using 1 Effort.*

Cypher: |
Spend
3pt then Difficulty -1 (TN -3) |

d6: |
Spend
3pt then Difficulty -1 |

##
__Edge
1__

__Edge 1__

*Example: Trying to reduce the Difficulty by -1 and Edge 1 applies.*

Cypher: |
Spend
2pt (instead of 3) then the difficulty is -1. |

d6: |
Spend
2pt (instead of 3) then the difficulty is -1. |

##
**Bonuses**

**Bonuses**

Bonuses
are a tricky conversion because it's the only place I've noticed so
far where a number directly effects TN result and not difficulty.
Tentative conversion is to treat each bonus as an Edge specific to
the situation

*Example: Bonus of +2 used to expend Effort 1.*

Cypher: |
+2
to the d20 roll. |

d6: |
Bonus
of +2 lets you spend only 1point to (3-2=1) to reduce the
Difficulty one step. |
