How can make the unlimited all

Hello @Tanimahmed Welcome to the community!

There is no event in this game that will give players "unlimited all", nor is there any means to purchase unlimited all. It would be very powerful and allow players a huge advantage in leaderboard competitions to have unlimited party poppers for example. This is why King limit the duration of UFO and party popper boosters to just 5 or 10 minutes when we do earn them.

Half hour of unlimited pre level boosters can be purchased with gold bars from your inventory and often the daily treat machine will give you an unlimited colour bomb for half an hour. But nothing gives players unlimited all I am afraid.
