Super 66 is an Australian lottery game played in all states except New South Wales (which plays Lotto Strike instead). It is a product of Tattersalls and is played on a Saturday night, drawn just before the main Tattslotto draw. Super 66 cost $1 per game plus agent's commission.

Super 66 must be bought as a computer generated entry in all states except South Australia (where numbers can also be selected through an entry form). The most popular option for buying Super 66 is with another lotto ticket - in this case, the Super 66 entry is usually printed on the same ticket. (Some states offer the ability to buy Super 66 with a mid-week ticket, as well as with the Saturday draw.)

In the draw, six numbers from 0-9 are drawn from six separate machines, creating a six-digit "winning number". To win First Division, a player must match the six-digit number on their entry with the "winning number" exactly. For example, if your ticket number is 0 5 3 4 8 9, the winning number must be precisely 0 5 3 4 8 9 to win First Division.

Lower divisions are won by matching the either first or last digits of the number on your ticket with the drawn number. For example, if your ticket number is 0 5 3 4 8 9 and the drawn number is 0 5 3 4 3 6 (matching the first four digits), then Third Division is won. The divisions are:

First Division (Jackpot, minimum $16,666.00) - All six digits matched in order.
Second Division ($6,666.00) - Either the first five or last five digits matched in order.
Third Division ($666.00) - Either the first four or last four digits matched in order.
Fourth Division ($66.00) - Either the first three or last three digits matched in order.
Fifth Division ($6.60) - Either the first two or last two digits matched in order.
 
Note that unlike most Australian lottery games, all prizes have a fixed amount, with the balance of the prize pool divided among Division 1 winners, or jackpotted if there are none. This means that First Division prizes can be as high as $100,000 or more. However, if the First Division jackpot is not won for five consecutive weeks, the Jackpot pool is "rolled down" to the next highest division with winners in the fifth draw.
