Tyrannos rules

Tyrannos is played on a 9×9 board with the following setup:

There are 4 different unit types:

  • (warriors) can reach one step towards the enemy base, orthogonally or diagonally
  • (heroes) can reach any number of unoccupied steps in any direction (like chess queen)
  • (barricades) can reach one step in any direction (like chess king)
  • (tyrannos) can reach one step in any direction (like chess king)

Each turn a player will select a unit and a square it can reach to either...

  • to the selected square
  • the selected square, killing an enemy unit there but leaving the selected unit where it is

There are some special rules:

  • No unit may ever move/attack diagonally unless they start on a dark square
  • may never attack or be attacked
  • may never stay on the central square (but they can move and shoot through it)
  • A reaching the enemy base is promoted to a

Win by killing the enemy !

The selected to the left can move diagonally since it is standing on a dark square.
But the selected to the right may not move diagonally (nor east since it is a warrior and east isn't closer to the enemy base)
