The Jurassic Battle Pass arrived with Update 5 in Grow a Chicken Fighter and stacks 100 tiers of rewards across a free track and a paid one. You earn EXP by clearing quests, and each tier hands over Cash, Charm Dust, Eggs, Amber Shards, and boosts. The pass is temporary, so the tiers you leave unclaimed disappear once it ends.
Quick answer: The pass has 100 tiers and levels only through EXP from hourly and daily quests. It closes on September 25, so claim everything before then.
Where to open the Jurassic Battle Pass and how long it lasts
Open the pass by tapping the Pass icon on the right side of your screen. It runs for two weeks and expires on September 25, so treat that date as your hard deadline for collecting every reward.
The pass splits into two reward tracks. Both hold 100 tiers, and both unlock the same way, by gaining EXP through quests. The Free Pass is open to everyone, while the premium track sits behind a Robux purchase.
Free, Premium, and Premium+ tracks compared
| Track | Cost | What it does |
|---|---|---|
| Free Pass | Free | Open to every player |
| Premium Pass | 35 Robux | Unlocks the premium reward track |
| Premium+ Pass | 99 Robux | Unlocks the premium track and skips 25 tiers |
The Premium+ option is the only one that instantly jumps you forward, granting the first 25 tiers of prizes the moment you buy it. Everything the paid tracks add sits on the premium reward line, so the Free Pass alone still delivers a full 100 tiers of items.
How to earn EXP and level the pass
EXP is the only thing that raises your tier. There is no other shortcut on the free side, so progress comes entirely from the missions listed in the Quests tab inside the Pass menu.
Quests come in two flavors. Daily tasks award more EXP than hourly ones but refresh every 24 hours, while hourly tasks cycle faster for smaller chunks. Most of them ask you to spend time in the game, hatch eggs, collect eggs from the Incubator, upgrade chickens, win Arena fights, and clear Tower floors.
Clear the daily quests first each day, since they give the largest EXP payout before resetting.
What the pass tiers reward
Every tier pays out something. The reward pool covers Cash, Charm Dust, Amber Shards, and a rotation of boosts including the Money Boost, Hatch Luck Boost, and Corn Boost. Eggs appear at set milestones as well.
Across the ladder you can claim Blazing Eggs, Dinosaur Eggs, Colossus Eggs, and Trick Eggs. A Dinosaur Egg lands at every tenth tier, meaning your first arrives at Tier 10 and continues at Tier 20, Tier 30, and onward on both the free and premium tracks.
Amber Shards are the currency that makes the pass worth finishing. They drop at tiers 3, 5, 8, 12, 14, 18, 22, 27, 31, 36, 41, 45, 49, 52, 56, 61, 66, 71, 76, 81, 86, 91, and 96, with larger amounts the higher you climb. Fully completing the pass hands you over 1,000 Amber Shards.
Spending Amber Shards on the Jurassic Crate
Amber Shards feed directly into the Jurassic Crate. Open the Pass menu and switch to the Crate tab to spin it. A single spin costs 125 Amber Shards and returns one prize from the pool based on your luck, with no pity system to guarantee the rare drops.
| Reward | Chance |
|---|---|
| 3.7M Gold Coins | 47.5% |
| 1x Fortune Egg | 25% |
| 250 Charm Dust | 25% |
| 1x Dinosaur Egg | 2.4% |
| Jurassic Pack | 0.1% |
The Jurassic Pack is the rarest pull at just 0.1%. It bundles 10 Dinosaur Eggs, 10,000 Charm Dust, and a secret chicken that wears a dinosaur helmet, making it the standout prize in the entire crate.
How to confirm your progress
You know a tier is unlocked when its reward becomes claimable in the Pass menu, and your Amber Shard total climbs as you collect them. Once you have enough shards, the Crate tab lets you spin and immediately shows the single item you received. Because the pass closes on September 25, work through the daily and hourly quests steadily rather than saving the whole ladder for the final day.
