Quick Answer: The Set Blast event adds a flat 30% bonus to all rewards earned from completing a card set. Because this bonus is so substantial, you should intentionally keep your card sets at 8/9 completion and only acquire the final card when Set Blast is active on your account.

Completing card sets is the primary way to earn massive spin payouts in Coin Master. But if you are completing them on a random Tuesday afternoon, you are making a grave mathematical error.

The Power of 30%

The Set Blast event is simple: it gives you 30% more rewards for completing a card set. If a set normally pays out 10,000 spins, Set Blast bumps that to 13,000 spins. That is 3,000 extra spins for doing absolutely no extra work.

The "Holding" Strategy

To master Set Blast, you must master the art of "Holding". When you get to 8/9 cards on a set, stop actively trying to complete it.

  • If the final card is a regular card, arrange a trade in a Facebook group, but tell the person: "Hold the card until Set Blast triggers."
  • If you have a Joker Card, hold it. When Set Blast activates, use the Joker to complete the set instantly. Read our Joker Card Guide for more tips.

Tracking the Event

As discussed in our Daily Events Calendar Guide, Set Blast is a flash event. It doesn't last all day. It will randomly pop up for 1 to 2 hours.

Ensure you have push notifications enabled for Coin Master. Often, the app will send a notification that Set Blast is active. When you see it, drop everything, log in, execute your trades, and cash in your sets for maximum profit.
