Daily Login Rewards
Use a server-managed Player Store cooldown to limit claims to once every 24 hours. This example increments a claim index and grants 120 standard tokens each time. The index records successful claims; it does not define a rotating reward schedule.
Define the Daily Reward Index
In Tools → TurnKit → Configuration → Player Store Defs, create daily_reward_index as a NUMBER. Disable client writes, enable client reads, and set cooldown duration to PT24H. The definition displays this cooldown as 86,400 seconds.

Create the Login Transaction
In Player Store Tx Catalog, create an enabled transaction named daily_login. Add both mutations:
daily_reward_index → ADD → 1token → ADD → 120

Claim the Reward
Call the transaction from the authenticated player context when the player claims. Handle the cooldown response as “already claimed for this period.” Because the cooldown is configured on daily_reward_index, keep that key server-managed.
var result = await PlayerStore.Transaction("daily_login").Execute();See Player Store for transaction rules. If your game has a multi-day reward calendar, use the incremented index in server-side logic to choose the next reward; do not trust a client-selected reward amount.
