Skill TicketsEditSkill Tickets can be applied to the Skill Level of the Tsum of your choice (Happiness or Premium). To use a Skill Ticket, choose a Tsum as your MyTsum, open the Skill Ticket message in your Mail Box, and click "OK" to confirm. Skill Tickets are the most valuable tickets in the game because they are applied to a specific Tsum's Skill Level, as opposed to Happiness or Premium Tickets which select a random Tsum. Skill Tickets are yellow.
Skill Tickets do not increase the Skill Level by a whole level. It will increase by the same amount a Happiness or Premium Box would have increased it. Tsums can require over 20 boxes to reach the next Skill Level.
Item TicketsEditItem Tickets can be used to purchase Item Boosters, like +Score, +Coin, or +5>4, for games. When you have an Item Ticket, on the Bonus Items screen there is a blue ticket where the price of the Item usually appears.
