About the Draw

What is a Catch the Ace raffle?

Catch the Ace is a progressive, weekly raffle lottery where participants purchase tickets that are associated with envelopes on the gameboard. There are 52 envelopes on the gameboard and each envelope hides one card from a standard deck of 52 playing cards. Tickets are purchased each week and draws are conducted weekly until the Ace of Spades is found.

How do I win?

Envelope reveals any card but the Ace of Spades:

If the participant’s envelope reveals a card other than the Ace of Spades, the participant will receive the weekly jackpot (20% of gross weekly sales). At this point:

  1. The envelope and card is removed from the gameboard
  2. The progressive jackpot (30% of gross weekly sales) for that draw is rolled over into the next scheduled draw. The progressive jackpot continues to grow until the Ace of Spades is chosen.

Envelope reveals the Ace of Spades: 

If the participant’s envelope reveals the Ace of Spades, the participant will receive both the weekly (20% of gross weekly sales) and the entire progressive jackpot accumulated. Once the Ace of Spaces has been unveiled, the raffle is concluded.

How much are tickets?

5 for $10 – Good Value ($2.00 per ticket)
20 for $30 – Better Value ($1.50 per ticket)
40 for $40 – Best Value ($1.00 per ticket)

There is no limit to the number of tickets available.

When is the ticket sales deadline?

Tickets will be available for purchase until 8:00 p.m. every Thursday until the Ace of Spades is found.

When do ticket sales start up again?

If the Ace of Spades is not unveiled, sales for the following week will commence at 1:00 p.m. on Fridays.

How is the winning number drawn?

The weekly winning ticket will be drawn using Random Number Generator under the supervision of MNP LLP every Friday at approximately 12:00 p.m. Records of MNP LLP shall be deemed correct and final if there is a discrepancy in numbers.

At approximately 12:05 p.m. the Catch the Ace display case will be opened, the envelope associated with the winning ticket will be removed from the board and the sealed envelope will be opened to reveal the card inside.
