❗19. What is The Grand Building Event?
Grand Building is a new server-wide event where Rollers join forces to build something that won’t simply disappear once the event is over.
The idea is simple:
use eligible items to support the construction;
earn Grand Building Points (GBPoints);
and turn those contributions into real construction progress.
But Grand Building has more going on beneath the surface. Your GBPoints can push the building forward, move you up a Stage Leaderboard, and progress your BuildPass. And knowing when they count toward each one can completely change your strategy.
What is The Grand Building?
Grand Building is one massive construction project shared by Rollers on the same server.
The event is divided into four consecutive Stages, and every Stage represents another part of the build. The server starts with an unfinished construction site and gradually transforms it as more resources are contributed and more GBPoints are added to the project.
Everyone is working toward the same building, but your individual contribution still matters.
GBPoints move you through the BuildPass and determine your position on the current Stage Leaderboard. You don’t need to complete every BuildPass level to receive rewards. Once all four Stages of the Grand Building are completed, you’ll receive all the BuildPass rewards you unlocked based on your progress.
And every Stage is a fresh chapter.
Once one construction phase reaches 100%, its Leaderboard closes, its rewards are settled, and the next Stage begins with a brand-new Leaderboard. The BuildPass, however, continues across all four Stages.
Contribute with items, earn GBPoints, build the next Stage
The Recipe shows the types of items currently needed for construction. Depending on the Stage, different eligible categories can appear, including things such as Miners, Racks, Hamsters, or special event resources.
From the contribution panel, you choose what you want to use and can see how many GBPoints those items will generate before confirming.
Then comes the important part: when you press Build, those selected items are consumed.
Once contributed, an item is permanently removed from your inventory and converted into GBPoints according to its value in the current Recipe.
Different items can also be worth different amounts of GBPoints, so this isn’t simply about throwing anything you have into the construction site. Check what the Recipe needs, check what your items are worth, and decide what makes sense for your goal.
Maybe you want to help finish the Stage. Perhaps you’re fighting for a Leaderboard position. Or maybe that BuildPass is your real target.
And that distinction becomes very important once the server starts getting close to its limits.
Four Stages, one construction
Grand Building isn’t completed in one giant push.
The Hamsters GYM is built across Stage 1, Stage 2, Stage 3, and Stage 4, with every step taking the construction closer to its final form.
The progress of the active Stage is shown as a percentage below the Stage icon. That percentage represents how close the server is to completing the current construction phase.
When it reaches 100%, the Stage is done. For the first Stage, Rollers will collectively need: 150 000 000 GBPoints
That number isn’t currently displayed directly in the event interface, so we’re including it here to make the first construction target clear.
As the percentage rises, the building itself evolves too.
The project begins as a construction site and gradually receives more of its structure, machinery and final details as the community moves through the Stages. By the time Stage 4 is complete, what started as a blueprint becomes the finished Hamsters GYM.
The basic journey is:
Base → Stage 1 → Stage 2 → Stage 3 → Stage 4 → Finished
Once a Stage is completed, there’s no going back to its progress. The construction moves on, a new Stage opens, and the next part of the job begins.
Every Stage is a new Leaderboard race
Grand Building may be cooperative, but nobody said the construction crew couldn’t compete.
Each of the four Stages has its own separate Leaderboard.
Your ranking is based on the GBPoints that successfully count toward the current Stage Leaderboard. The more eligible points you generate while that Stage is active and within the global limit, the higher you can climb.
When the Stage reaches 100% completion, the race ends.
The Leaderboard is finalized and the corresponding Stage rewards are credited based on the final standings. Then the next Stage opens with a new Leaderboard and a new opportunity to compete.
So your position does not simply carry through all four construction phases.
A great Stage 1 gives you the rewards and bragging rights for Stage 1, but when Stage 2 begins, the race starts again.
The BuildPass is one long run
While the Leaderboard resets every Stage, the BuildPass does not.
There is one Grand Building BuildPass running across all four Stages, so the GBPoints you earn throughout the entire event keep pushing its progression forward.
The BuildPass includes Free and Premium tracks, with the Premium track covering the whole Grand Building event rather than an individual Stage.
The GBPoints you earn from accepted Grand Building contributions also move your BuildPass forward.
That makes checking the current Recipe especially important. Once one contribution category reaches its limit, you’ll need to look at the categories that are still available if you want to keep earning GBPoints.
BuildPass rewards are unlocked when construction is complete. The rewards become available once all four Stages are completed and the Grand Building is fully constructed.
You do not need to complete the entire BuildPass to receive rewards. Even if you finish only part of it, you will receive all rewards unlocked through the levels you reached.
For example, if the BuildPass has 40 levels and you reach level 39, you will receive the rewards for those 39 completed levels once construction is finished.
Complete the construction to unlock BuildPass rewards
Grand Building’s BuildPass does not pay out rewards level by level as you progress.
BuildPass rewards become available once all four Stages are completed and the Grand Building is fully constructed.
You do not need to complete the entire BuildPass to receive rewards. You will receive all rewards unlocked through the levels you reached.
For example, if the BuildPass has 40 levels and you reach level 39, you will receive the rewards for those 39 completed levels once construction is finished.
So keep earning GBPoints to unlock as many BuildPass rewards as possible before the Grand Building construction is complete.
Finished the BuildPass? Don’t forget to claim
Completing the final level is also not the last action.
BuildPass rewards must be claimed manually.
They are not automatically sent to your account just because you completed the Pass.
Finish the whole thing, then make sure you actually collect what you earned.
It’s a small action, but probably not one you’ll want to remember five minutes after the event has already ended.
Meet the Lunch Box
A construction crew needs fuel, apparently.
Grand Building introduces the Lunch Box, a special event resource that can appear as one of the items required by a Stage Recipe.
Lunch Boxes are made specifically for Grand Building Recipes. They are stored among your Utility Items and can be obtained through different activities running around the event, such as Forge, Puzzle Events, Progression, Burning, Resource Well, offers, and other event sources.
Their purpose is simple: when a Stage Recipe asks for Lunch Boxes, you can contribute them to the Grand Building just like any other eligible resource. They have no separate use outside the Grand Building Recipe.
When the event ends, any unused Lunch Boxes expire and are removed from your inventory.
So if you’ve been stockpiling enough lunches to feed an army of Hamsters, make sure that army actually eats before construction closes.
