How to earn Windborn Stamps in Aniimo
Alphas, Hollow Sim battles, Homeland orders and Tea Time all pay Windborn Stamps, and 2,500 spent in the Stamp Exchange unlocks the Sparkling Cube.
The short version
- Windborn Stamps come from ordinary play: catching Aniimo and expending energy both earn them, before you go looking for anything special.
- The Stamp Rush list in the Institute Guide is your checklist, and it includes turning in Aniimo reports and fighting Ultra Aniimo.
- Defeating Alpha Aniimo, Hollow Battle Sim and Hollow Battle Interlink fights, and wild surges all award Windborn Stamps.
- Homeland daily orders and Tea Time at the Astra cafe pay stamps with very little effort, and Tea Time also gives up to 150 Voxel Coins per day.
- The Sparkling Cube (also called the Shiny Cube) yields Sparkling eggs and unlocks once you have spent 2,500 stamps on items in the Stamp Exchange.
Windborn Stamps are the seasonal currency that feeds the Stamp Shop, and the shop is where the Sparkling Cube lives. You earn them almost everywhere. That is good news, but it also makes it easy to miss the sources that pay well for the time they take.
This guide walks through every activity that awards Windborn Stamps: the passive trickle from normal play, the Stamp Rush list, Alpha Aniimo and Hollow battles, Homeland orders and Tea Time. It finishes with the reason most players are counting stamps in the first place, the 2,500 stamp Sparkling Cube unlock. How stamps sit alongside the game's other currencies is covered on its own page, so this one sticks to earning them.
Stamps from everyday play
You start earning stamps without trying. Catching Aniimo awards them, and so does expending energy, so a session spent exploring and catching is already filling your balance.
On top of that baseline, stamps come from season achievements and activities, daily activities, Stamp Rush and the companion handbook. Daily activities are the reliable part of that list because they come back every day. Season achievements are worth checking now and then, since they pay out as you hit goals you may be working towards anyway.
Stamp Rush in the Institute Guide
Stamp Rush is the closest thing the game gives you to a stamp checklist. Open the Institute Guide and the activities listed under Stamp Rush are the ones that award Windborn Stamps. Two of them are turning in Aniimo reports and fighting Ultra Aniimo battles.
The Stamp Rush event is also its own source of stamps. If you only have time for a few things in a day, the Stamp Rush list is the place to start, because everything on it is there precisely because it pays stamps.
Alpha Aniimo, Hollow battles and wild surges
Combat is a steady earner. Defeating Alpha Aniimo awards Windborn Stamps, which gives you a stamp reason to take on an Alpha whenever you find one.
Hollow battles pay too. Both Hollow Battle Sim and Hollow Battle Interlink award Windborn Stamps, so either mode counts. Wild surges round out the combat sources. Between Alphas, Hollow fights and surges, a player who enjoys battling can keep stamps coming in without leaning on daily chores.
Homeland orders and Tea Time
The low effort sources live at home. Homeland daily orders award Windborn Stamps, and fulfilling Homeland production and delivery orders more generally awards Home Coins, stamps and progression resources. That makes orders one of the better uses of a short session: you advance your Homeland and collect stamps in the same step.
Tea Time at the Astra cafe is even easier. Attending it passively awards Windborn Stamps, along with up to 150 Voxel Coins per day. The Voxel Coins from the Starcross Tea Party coffee shop event are likewise capped at 150 per day, so once you hit that cap, any further visits that day are about stamps, not coins.

The 2,500 stamp Sparkling Cube unlock
This is where your stamps go. The Sparkling Cube, also called the Shiny Cube, sits in the seasonal Stamp Shop and yields Sparkling eggs. It is not available from the start. It unlocks after you spend 2,500 stamps on items in the Stamp Exchange.
The word that matters there is spending. Earning 2,500 stamps and holding them does not open the Cube; the stamps have to go on items in the Exchange first. If the Sparkling Cube is your goal, buy what you would want from the shop anyway and let those purchases carry you to the unlock.

Where to start
Do your daily activities and Homeland daily orders, stop by Tea Time, and work through the Stamp Rush list in the Institute Guide. Fight Alpha Aniimo and Hollow battles whenever they come up. Then spend your stamps in the Stamp Exchange instead of saving them, because 2,500 spent is what unlocks the Sparkling Cube.
