Officially listed strings
The current official game description lists Crystal and Relax as new codes. The official listing text does not publish their rewards, so the page reports the strongest current cross-source result instead of pretending every reward amount is settled.
How to redeem
Open Steal a Chicken on Roblox, look for the in-game codes or rewards menu, enter one code exactly as shown, then submit it once. Check the in-game confirmation toast before treating a disputed reward amount as exact, because community reports currently disagree on some values.
Reward evidence
Release is consistently reported as 100K Cash. Relax is consistently reported as a x2 Money, x2 Speed, and x2 Growth boost.

Check the in-game confirmation toast before treating a disputed amount as exact.
