Systems are available for Lotto through fewer numbers entries (Systems 4 to 5) or more numbers entries (Systems 7 to 20). To buy a Lotto Systems ticket:

Mark the System number you wish to play on a Millionaire Medley Playslip. Then mark a game board with the appropriate amount of numbers for the System (4 to 5, or 7 to 20) and the day you wish to play (Monday, Wednesday and/or Friday).

Ask for a Millionaire Medley Systems Slikpik in-store and a ticket will be issued with randomly generated numbers for you.

Log in to your Lotterywest membership to choose your own numbers or request a Systems Slikpik.

In System entries with fewer numbers, your selection of numbers is then combined with all remaining numbers (1 to 45) to create every possible six-digit combination containing your selected numbers.

In System entries with more numbers, your selection of numbers are used to create every possible six-digit combination containing your selected numbers.
