In the event, you’re supposed to go through 25 levels and pick one of the four chests. Three of them contain rewards, but one is protected by the Red Guard. If the Red Guard catches you – you will lose all the rewards. 

How to participate in Vault Heist?
To enter the event, you need to spend 10 bombs (= entry tickets).
You can earn the bombs by:
- Raiding dungeons (sometimes you will receive bombs as an additional reward)
- Entering the game for the first time during the day (you will receive10 bombs)
- Spending orbs (1 bomb costs 5 orbs)

How do you escape from the Red Guard?
You will be offered to give him orbs to get away and continue to participate in the event and collect the rewards. The number of orbs required will increase with each Red Guard you encounter. The first time you are caught, you may be offered the chance to escape from the Guard by watching an ad. However, this option is not guaranteed and appears rarely.

There are 25 levels in the event: 19 regular levels and 6 “green” ones. On a green level, there is no Red Guard, these are safe levels. In addition, “blue” levels can sometimes  appear: these are the levels without the Red Guard, but to open them you have to watch an ad.

What rewards can I find in the chests?
All the resources available in the game:
- Gold
- Unique gems
- Ingredients
- Potions
- Gems
- Tears
- Emeralds
- Orbs
- Keys
 You may sometimes be offered to double your reward for watching an ad. If you refuse, you will receive the usual number of the items you were given.

All the rewards in the chests (for each level) are shown before they are shuffled. After shuffling, the rewards in each chest are also shuffled.

The rating of gems received in the event is summed into one gem. For example, if you received a 60 000 rating gem and then a 80 000 rating gem, when you leave the event you will receive one 140000 rating gem.

How do I leave the event?
On each level, after the chests have been mixed, you have the option to press the Take and Leave button. This will give you all the rewards you have collected.

If you quit the game while passing the event, your progress will be saved, and you will start at the same level the next time you play. This also works if you press the X button in the top right corner of the event screen.
