When you load the game you'll first see a settings menu with options:
- Set the price for each piece by changing the values.
- Set the quantity for each piece

Placement

- Anywhere on backrank
Pieces may be placed anywhere on the backrank of the player. 
(white player buys a rook on the e file: $Re1)
- On original spot:
A piece may only be placed on a spot he started the game on.
(white player buys a rook on the h file: $Rh1)
 

Promotion

- Steal cash
When a pawn reaches the opponent's backrank the player gets all the opponent's savings added to his. 
(White pawn hits c8. Black has 30 coins in savings, they are added to white's savings. The pawn is removed from the game.)
- Normal promotion
When a pawn reaches the opponent's backrank the player gets a piece of his choice 
(A black pawn hits a1. The player chooses a queen and replaces it for the pawn) 
- Steal Cash and promote
When a pawn reaches the opponent's backrank the player steals the opponent's savings and he gets a piece of his choice.  
(white moves a pawn on c8. Black has 30 coins in savings. White gets the 30 coins and he chooses a queen to replace the pawn.)

Production

- May always produce (recommended setting)
Both players may choose to produce in their turn.
- Production square dependent
Only the player who owns the h4 square may produce 
(This is a variant that has not been fully developed. The idea was to place special tiles acros the board that allow/disallow building or gain extra income.)

Movement

- Produce AND move
A player may first produce and also move (with the new piece as well) afterwards. A player may place purchased pieces to block the king from check. 
(white player buys a rook on the e file: $Re1, he moves: 23. Re8)
- Produce OR move (recommended setting)
A player may choose to buy piece(s) or move a piece.
The player must move when the king is checked.
(white player decides not to move and buys a rook on the h file ($Rh1) and a pawn on the e and h file ($e2 + $h2))
