Bottleneck Order
Start by naming the blocker. Space blockers prevent dinosaurs from being used. Recovery blockers make every next egg feel too expensive. Flow blockers happen when dinosaurs exist but visitors are not turning them into Cash quickly enough. Each blocker points to a different upgrade category.
A good upgrade creates a visible before-and-after result. After buying, the park should fit another dinosaur, recover Cash faster, or make the next egg route clearer. If the effect is cosmetic or hard to notice, it belongs later in the route.
| Blocker | Upgrade priority | Test after buying |
|---|---|---|
| No room for useful dinosaurs | Land, pen, or placement capacity | Can the next hatch be used immediately? |
| Cash recovers slowly | Income or visitor-flow improvement | Does the next target arrive faster? |
| Too many weak dinosaurs | Replace through eggs before cosmetic spending | Does a new dinosaur improve recovery? |
| Rewards waiting unused | Upgrade only if it unlocks the reward plan | Does it support Frozen Egg, Teeth, or Cash route? |
Upgrade vs Egg
Buy an egg when the park can place and profit from the result. Buy an upgrade when the next egg would be delayed by space or recovery. This simple split prevents the most common early waste: buying a better egg while the park cannot use it, or buying an upgrade when another dinosaur would have improved income faster.
If a code session gives you enough Cash for either option, choose the option that fixes the current bottleneck. UPDATE2 is large enough to tempt a jump. The safer play is to check space, hatch status, and recovery before spending the reward.
Update 2 Rewards and Upgrades
Update 2 code sources report Teeth and Frozen Egg rewards. Those rewards make upgrade timing more important because a reward can create a sudden capacity problem. If the Frozen Egg produces a dinosaur that deserves space, an upgrade may beat another egg. If Teeth point toward a shop purchase, wait until the Store path is clear.
Do not upgrade blindly after codes. Use the reward, observe the changed park state, and spend the next batch on the blocker that remains. A strong reward can shift a player from egg scarcity to space scarcity in one session.
| Reward state | Likely next check | Why |
|---|---|---|
| Frozen Egg hatched into useful dinosaur | Space and placement upgrade | The dinosaur needs to work now. |
| Cash is high but income still slow | Visitor-flow recovery | More balance does not fix slow income by itself. |
| Teeth available | Store target review | Limited currency should solve a specific target. |
Upgrade Mistakes
The weak upgrade pattern is spending because the button is available. The strong pattern is spending because the route has a named blocker. If a player cannot say whether the purchase improves space, recovery, or income flow, the purchase can wait until one more hatch or code session gives better information.
