Rushbox: a crypto casino where every spin fills a key
Book a call, get a price rangeRushbox is a crypto casino built around slots, for players who grew up opening cases. A slice of every spin fills a key, a full key airdrops a case onto the reels, and the case opens on a strip of items graded from grey to gold. We built it from scratch: the name, the open-box logo, the house slot Supply Drop in 13 states, the platform and its phone screens, a 3D kit in Blender, the interface motion in Rive, and the launch on an arena screen, a team jersey and a VIP hard case.

Slots with a case drop in every spin
Rushbox is a crypto casino built around slots, for players who grew up opening cases in competitive shooters. A slice of every spin fills a key, and a full key airdrops a case onto the reels.
The case opens on a horizontal strip of items and pays crypto, free spins or a collectible charm, with no wagering. Every win is graded like an item, from grey to gold. Red and gold wins post to the live feed and pin a holo sticker to the player's profile.
Responsible play is part of the product: 18+, limits on the deposit sheet, session reality checks, published RTP and a provably fair seed on every round.
Three rules every screen follows
- The spectrum belongs to items
- Grey, light blue, blue, purple, pink, red and gold appear only on items and wins. The chrome stays gunmetal.
- Yellow means money or action
- Hazard yellow is kept for deposit, spin and open.
- Cases, keys and charms carry the feel
- Hard cases with latches, keys, keychain charms and holo stickers. There are no weapons, no fruit-machine symbols and no game company's marks, maps or names.
Key, drop, strip, grade
The whole loop plays out on the slot screen, so the player never leaves the game to open a case.
The key meter sits under the reels and fills one tooth at a time. When it's full, a case on a yellow parachute lands on the reels and the spin button becomes OPEN CASE. The item strip rolls under one yellow line and stops on the prize. The reveal names the grade and its odds before the player collects.

Supply Drop, the house slot
Supply Drop is the flagship Rushbox Original: five reels, three rows and a case on every screen.
Rush, the robot keychain charm, is the wild, and the case is the scatter. The high pays are a trophy, a key, a headset and a dog tag, and the low pays are vinyl stickers. In the bonus, three cases airdrop in and open on the strip, and their multipliers feed the free spins.
We drew 13 states, from idle to max win. A big win climbs four words, BIG, MEGA, EPIC and MAX, each in the colour of its grade.



Lobby, inventory and the VIP road
Around the slot sits the casino: a lobby of Rushbox Originals, an inventory of every drop, a wallet and a VIP road.
The lobby opens on the player's key and the live drops. Every case a player opens lands in the inventory, where a charm can hang on the profile or be sold back. The VIP road uses the same seven grades as the drops, and each rank is a case.



The same drop, one thumb
On a phone the reels take the screen, and the key sits between them and the button.
The deposit sheet shows the daily limit on the same screen as the address. Raising a limit takes 24 hours, and lowering it is instant.




A box with its lid popping open
The symbol is a hard case caught as it opens, drawn on 15-degree axes from one module.
Every radius and gap comes from the same 7-unit module, so the lid, the latch and the two burst lines hold together at any size. Below 33 pixels a small cut opens the gaps, and at 16 pixels a micro cut drops the latch.
The wordmark's letters are drawn as bezier outlines. The logo comes in white, ink and hazard yellow, and the rarity spectrum never touches it. The interface is set in Hubot Sans, with stencil headlines in Big Shoulders Stencil.



Built in Blender and Rive
Everything that moves in the product is ours: a 3D kit written in Python and rendered in Blender, and the interface motion rigged in Rive.
The kit has the case in eight light-strip colours, the key, the parachute, the item cards, the ten slot symbols, six VIP ranks and Rush. One light rig lights all of it, and the graphite stays cool.
Rush, the key meter, the spin button and the win ladder are Rive state machines in one file. The key fills one tooth per 10% and pops solid yellow when it's full. The spin button rolls from SPIN to STOP to OPEN CASE and turns its keyhole.


An arena, a team kit and a case for VIPs
Casinos sponsor football clubs and streamers. Rushbox is gamer-native, so it shows up on an esports stage, a team jersey and a slot stream.
The VIP gift is a real Rushbox hard case, rendered from the same Blender kit. The arena screens and the stream overlay are built in HTML from the kit and the UI.
The arena, the jersey, the unboxing, the hoodie, the charm and the poster plates are generated photographs, with our artwork and the real logo laid in.










The identity board, as a 10-second film
The board leads with the product: the slot at the drop, the case opening, the reveal on a phone, the app icon and the team kit.
It loops for LinkedIn and X.
Credits and how it was made
Brand, product and launch, made by the Alterra Studio team over two days, 21 and 22 October 2026.
Generated pictures set the world's look and gave us the photo plates for the arena, the jersey, the posters and the merch. The rest is built: the 3D kit in Blender, the motion in Rive, the screens in HTML and the logo as vector outlines.
