Erdös Latino is played on an initially empty 5×5 board.

There are 5 units, ranked level 1-5 from left to right like this:

Each turn, a player will place a new unit:

• place1 - place a level 1
• place2 - place a level 2
• place3 - place a level 3
• place4 - place a level 4
• place5 - place a level 5

The only rule is, you may never place a unit in a row or column that already has a unit of that type. Think Sudoku!

If the game ends with the players unable to fill the board because of this rule, the last player to place a unit wins via starvation.

But, if the board is completely filled, the player controlling the most columns win via columncount.

This clever tiebreaker works like this:

• When you place a unit, if that forms an ascending ranking of 3 or more units in the column, you get control.
• It is ok to skip levels, so 1 3 4 would give you control.
• It is ok to have empty squares or even other units inbetween. 1 _ 4 3 5 gives control through 1, 3 and 5.
• Player 1 gets control for ascending rankings from the bottom of the board and up
• Player 2 gets control for ascending rankings from the top of the board and down
• Units in controlled columns become the colour of the controlling player
• Once a column is controlled it will stay controlled by that player
• It is possible to give the opponent control through careless placing
• If placing a unit would give both players control, it goes to the active player
