Collection Books

How to complete

• Each book defines the prize requirements for its slots.
• Each book has its own deadline. New deposits and reward claims are blocked after it ends.
• Eligible prizes usually need to match both the required series and prize tier.
• Prizes must match the slot requirement and must not be redeemed or locked by another flow.
• Deposited prizes become locked by the collection book and cannot be redeemed or redrawn at the same time.

Claim rewards

• When every slot is completed, the configured book reward can be claimed.
• Each collection book reward can be claimed only once and cannot be claimed again after completion.
• After claiming, the deposited prizes are considered used to complete the quest and cannot be withdrawn.
• Rewards are issued by the collection book rule and may be Doudo Points, a specific prize, or another campaign reward.
• Prize rewards are always claimed as one item.
• Prize rewards are usually also tied to a specific series and prize tier.
• Prize rewards belong to the configured reward series, which may differ from the deposited prize series.

Locking and withdrawal

• Deposited prizes are shown as locked by the collection book in your account.
• If withdrawal is supported, you can withdraw deposited prizes from the book page.
• Withdrawing lowers progress, so the book must be filled again before claiming.
