RollerCoin Grand Building: how it works and how not to waste items
Grand Building is a server-wide construction project. Players contribute items, earn points and, together, unlock something that stays in the game after the event. The first project was the Hamster Gym. Since contributed items are gone for good, it is worth knowing the rules before you click Build.
How the event is structured
The project has four consecutive Stages. Each Stage has a Recipe with item categories and a GBPoints target. The first Stage needed 150 million GBPoints across the whole server.
| Part | How it works | Resets each Stage? |
|---|---|---|
| Construction progress | Shared percentage of the current Stage | Yes, moves to the next one |
| Stage Leaderboard | Ranks your GBPoints in that Stage | Yes, each Stage has its own |
| BuildPass | Personal progress, free and premium tracks | No, runs through all four Stages |
The key rule: categories have limits
Each Recipe category (such as miners, racks, hamsters or special resources) has a limit for the whole server. Once reached, that category closes for the current Stage: you cannot contribute from it and you earn no more points from it.
In practice, this changes your strategy. If you are competing on the leaderboard, watch which categories are still open and which are close to closing. Contributing early in a contested category can be worth more than waiting for the end of the Stage.
How to decide what to contribute
- Check the Recipe: the screen shows open categories and points before you confirm.
- Compare what you lose: a contributed item is removed forever, just like in a burn.
- Start with what you do not need: copies, miners outside your room and idle resources.
- Protect unique bonuses: the same logic of the copies guide applies here.
- Set a goal: leaderboard and BuildPass need different efforts.
Leaderboard or BuildPass?
| Goal | Best for | Risk |
|---|---|---|
| Stage Leaderboard | Players with many items to contribute at once | Your rank does not carry to the next Stage |
| BuildPass | Players who contribute a little, but steadily | Rewards only come when construction ends |
| Just help the build | Players who want the result without competing | Few personal rewards |
BuildPass: three easy-to-miss details
- Rewards unlock only when all four Stages are done.
- You do not need to finish the pass. If it has 40 levels and you reach 39, you receive the rewards of those 39.
- Claiming is manual. If you do not click to claim, the reward does not reach your account by itself.
Lunch Box
The Lunch Box is a resource made for the build, stored in your Utility Items. It comes from activities such as Forge, puzzles, progression, burning and offers. It is only useful for Grand Building Recipes and it expires when the event ends. So do not save it: use it while a Recipe accepts it.
Checklist
- Check the time left on the home page.
- See which categories are open.
- Set aside what you can contribute without losing power.
- Use your Lunch Boxes before the event ends.
- After the end, claim your BuildPass.
