Everyone digs the same cube at once. Every power tool bought adds its price to a shared pot, and whoever lands the hit that destroys the final block takes the whole thing. The payout runs on Robinhood Chain, on its own.
Quick Start
- Hold. You need 1,000 $CUBE in your wallet to get in the door.
- Connect. Connect an EVM wallet like MetaMask on Robinhood Chain and sign the message it asks for. That signature just proves the wallet is yours and holds the token. It moves nothing and costs no gas.
- Dig. Tap a face to zoom in, then start breaking blocks. Every block you break pays out coins.
- Power up. Coins buy the brushes. $CUBE buys the heavy stuff (Drill, Bomb, Nuke), and that spend goes into the pot. These are on-chain buys, so keep a little ETH in the wallet for gas.
- Win. The cube peels back one layer at a time. Break the last block and 95% of the pot lands in your wallet.
Two currencies to keep straight: coins are earned in-game and stay in-game; $CUBE is the real token, and it's what the pot is made of.
The Cube & Its Layers
128 blocks to a side, which works out to 64 layers between the surface and the core. Only the current outer layer can be dug. Clear enough of it and it peels off, and the layer underneath becomes the new surface. Then you do it again, 64 times, until there's nothing left.
Peeling a layer
On the big outer layers you don't have to hunt down every last straggler. Once a layer is down to 8 blocks or fewer, the game clears the rest and moves on. Deeper in it gets stricter: any layer under about 1,000 blocks has to be cleared to zero. Those inner layers are small and fully in view, so the endgame is a proper scrap, and the winning hit is a real block that someone actually broke rather than an auto-clear.
The Pot & The Payout
The pot is a vault on Robinhood Chain. Every $CUBE anyone spends on a power tool lands in it, so it climbs as the game goes on. There is no withdraw button. The only thing that moves tokens out is the payout, and that only fires when the cube is gone. The team can't send the pot anywhere else, by design.
The split
- 95% goes to whoever breaks the last block.
- 2.5% goes to a treasury that covers RPC, hosting, and keeping the lights on.
- 2.5% is burned, permanently removed from circulation.
One rule worth knowing before the endgame: power tools stay live to the very last block. There is no tool ban on the final layers, so clearing the last shell with a Bomb or a Nuke is a completely legitimate way to take the pot. If you're in the finale, assume someone has a charge ready.
The moment the cube falls you get the winning wallet, the amount, and a link to the on-chain transaction. Nothing to claim and nothing to wait for.
Coins and $CUBE
Coins earned in-game
You earn coins for breaking blocks. They live inside the game and can't be cashed out. What they're for: buying the brush tools, and building up your combos and daily streak.
$CUBE real token
The real token on Robinhood Chain, doing three jobs. It gets you in (you hold 1,000 to play), it buys the power tools, and it is the pot. Buy a Nuke and you've just made the prize bigger for whoever ends up winning.
Tools
The pick and brushes run on coins. They're your steady digging. The power tools cost $CUBE, wipe out a chunk of the layer in one shot, and every purchase feeds the pot.
| Tool | Cost | Price | Clears | Uses | What it does |
|---|---|---|---|---|---|
| Pick | Free | - | 1 block | Unlimited | One block per tap. Never runs out. |
| 3×3 Brush | Coins | 5,000 | 9 blocks | 30 uses | Clears a 3×3 patch. |
| 5×5 Brush | Coins | 10,000 | 25 blocks | 15 uses | Clears a 5×5 patch. Digs quicker. |
| Drill | $CUBE | 1,000 | a full line | 1 use | Bores a whole line straight down the face. |
| Firecracker | $CUBE | 2,000 | ~49 blocks | 3 uses | A star blast: cross plus diagonals. |
| Bomb | $CUBE | 50,000 | ~149 blocks | 1 use | A crater about 15 wide. |
| Nuke | $CUBE | 200,000 | ~908 blocks | 1 use | A hole about 35 wide. Not subtle. |
Power tools fire their whole shape at once and ignore the dig-rate limit the coin tools live under. That speed is what the $CUBE is buying you.
Coins, Combos & Jackpots
What a block is worth
Most blocks pay a single coin. A few pay more, and a rare handful pay a lot. What each block is worth is locked in before the season starts and never changes (see On-chain), so it's a treasure hunt with the odds printed on the box, not a live gamble.
| Tier | Odds | Coins | |
|---|---|---|---|
| Empty | 90% | 1 | Most blocks. The floor. |
| Shard | ~8% | 25 | A small hit. |
| Vein | ~1.9% | 250 | Everyone watching sees the gold burst. |
| Lode | 0.1% | 2,500 | Rare. |
| Motherlode | 0.01% | 50,000 | The jackpot. Announced to the whole room. |
Combos
Break blocks in quick succession and a coin multiplier builds. As long as each hit lands within about a second and a half of the last, it climbs from 1.5x at a 50 combo up to a 3x ceiling. Pause too long and it drops back to nothing.
Daily streaks
Break at least one block in a day and your streak ticks up. The daily bonus scales with it, 100 coins times the day you're on, and stops growing at day 7. New accounts start with two freezes to cover a day you can't play.
Fair Play
The server runs the real game. Your browser draws it and sends your taps, and that's the extent of it. It never tells the server what got cleared or what you earned, so a hacked client has nothing to lie about. Everything below sits on top of that.
Dig-rate cap
Coin tools are held to roughly 28 blocks a second per player, with a little headroom for short bursts, so nobody gets to machine-gun the board. Power tools skip the cap, which is the point of paying for them, and are limited by their charges instead.
Bots
Clicking like a metronome gets you scored and quietly throttled: an inhumanly regular cadence reads as a script, and a flagged account's clicks start silently failing, indistinguishable from ordinary rate limiting. Every wallet also needs 1,000 $CUBE to play, so a bot swarm carries a real price tag. And since the server re-derives every hit itself, a script can't claim anything a real click wouldn't have done.
The Entry Gate
You need 1,000 $CUBE in the wallet to play. Hit Play and it will ask you to sign a short message. That's a signature, not a transaction: no gas, nothing spent, nothing moved. It only proves you own the wallet and that it holds the token. If you'd rather just watch, Spectate is free and skips all of it.
Controls
- Overview. The on-screen arrows (or your arrow keys) spin the cube. Tap a face to drop into it.
- Zoomed in. Tap blocks to break them with whatever tool you've equipped. Zoom Out, or Esc, backs you out.
- Tools. Tap a card to equip it. Owned tools show how many uses are left.
- Hide UI. The Hide button, or the H key, strips the interface for a clean look at the cube.
On-Chain & Provably Fair
The pot is a small contract on Robinhood Chain built for this one job. Buying a tool is an ordinary token transfer into it. The only function that sends tokens back out is the payout, and it splits them between the winner, the treasury, and the burn exactly as above. Nothing in the contract can route the pot anywhere else. That's the whole reason it lives on-chain.
Provably fair rewards
Each block's reward comes from a secret. We publish a hash of that secret before a season and reveal the secret itself after. Take the reveal, replay the season's event log, and you can check every payout yourself. The odds are public before you start, and nothing gets rolled against you mid-game.
