How it works

$SWEEP is a memecoin on Injective. Every trade pays creator fees, and those fees buy NFTs straight off the floor. Each NFT becomes the jackpot of a Rumble. Holders who stake fight for it as cartoon brooms, and the last broom standing gets the NFT.

Staking is your ticket into the game. Every fighter stakes the same amount, so a bigger wallet is not a stronger broom.

• Exactly 250,000 $SWEEP. Not more, not less. One wallet = one broom.
• Counts right away. No waiting time: as soon as your stake is in, pick your class and join the next Rumble, and the daily quests open for you.
• Your tokens stay yours. They sit in the staking contract, and only your wallet can withdraw them.
• Unstake any time. Unstaking always takes the full amount; you can withdraw it 24 h after the request.
• Unstaking costs your level and XP. You go back to level 1 with 0 XP, a running level-up is cancelled and your secondary class is removed. Your class, items and companions stay. The stake page shows you exactly what you would lose before you confirm.

Go to the Stake page

Being staked does not put you in a fight by itself. You press Join once for every Rumble you want to fight in. Joining is free and sends no transaction.

• Only the current Rumble, the next one to be drawn, can be joined.
• As soon as it is drawn, the next Rumble opens for joining.
• Joining closes 60 seconds before the fight. Then the fighters are locked. The countdown on the start page shows “Join closes in…”, then “Fight starts in…”.
• No joining in advance and no auto-join. It keeps the arena full of players who are really there.
• Choose a class first. You need a class (in My Broom) before you can join.
• Your 250k must still be staked when the Rumble starts, and a Rumble needs at least 2 fighters.

A battle royale: every joined broom enters one arena at the same time, and the fight runs in rounds.

• Each round, every broom still standing acts in a random order: it attacks (40 %), sets a trap (25 %) or does something silly (35 %).
• Attack: your Ninja against the target's Speed. Trap: your Brains against the target's Brains. Every hit chance stays between 25 % and 75 %: nobody is safe, nobody is hopeless.
• 3 % of attacks and traps backfire and knock out the attacker instead.
• Knocked-out brooms can make a comeback once, thanks to Luck, until round 8.
• From round 8 a dust storm sweeps out about 15 % of the brooms each round; weaker brooms are hit more often.
• The last broom standing wins the NFT. If the fight is still going after round 40, a final showdown decides.

Everyone watches it live. The fight starts for everyone at the same moment and plays out on the start page in a few minutes. The big callout shows the knockouts and everything about your own broom one at a time; the last 3 brooms fight it out in the finale. No spoilers: the winner, the placements and the loot are revealed when the fight ends. Open the page mid-fight and you join at the current moment.

The whole fight is calculated from the draw block's hash, so it is the same for everyone and anyone can replay it in the browser. See Fairness & verify.

Everyone picks a class before their first Rumble: you can't join without one. Choose it in My Broom. Each class boosts one attribute, and every broom starts with 10 in each. You can switch class later for a $SWEEP fee.

Levels go from 1 to 20 and make your class stronger.

• Your class grows: +10 % per level from level 2. Level 2 = +20 %, level 10 = +100 %, level 20 = +200 % on your class's attribute.
• At level 10 you choose a second class. It must differ from your first one and grows +10 % per level: +10 % at level 10, up to +100 % at level 19.
• Level-ups take time. XP makes the next level ready; you start the upgrade and it finishes after a timer (1 h for level 2, up to 7 days for level 20). You can finish it at once for a fixed 100k $SWEEP, whatever the level.
• XPXP comes from the daily quests (trading brings the most), from Rumbles (+10 XP for every Rumble you fight in) and from your companion. Staking alone gives no XP.
• Unstaking resets your level. Back to level 1 with 0 XP, no running level-up and no secondary class. Your class, items and companions stay.

Your main class's attribute also gets the class match and set bonus of your items.

Your broom wears 4 items: hat, weapon, armor and shoes. There are 16 pieces of gear: every slot has one item per attribute, and each item has a signature attribute, shown by its badge. Swapping your loadout is free and instant.

All 16 pieces of gear

Rarity

An item boosts all 4 attributes, but its signature attribute gets much more. Items come from item chests: a chest picks a slot, one of its 4 items, then the rarity.

Class match & set bonus

An item whose signature attribute is the attribute of your main class is a class match: Shadow Sweeper Ninja, Lucky Bristle Luck, Zoom Broom Speed, Mind Sweeper Brains. My Broom marks these items with class match. Your secondary class does not count.

• Class match: the item's signature value counts +10 % (rounded, at least +1).
• Set bonus: wear more matching items for a bonus on your class attribute: 2 items +5 %, 3 items +10 %, 4 items +20 %.

Example: a level 11 Shadow Sweeper (+110 %) wearing 3 Ninja items and Ninja +26 from all items: (10 + 26 + 3) × 2.1 × 1.1 = 90 Ninja. The other attributes work as before. Stats are whole numbers (rounded once at the end).

Your bag

• Your bag holds your unequipped items: 30 slots to start (it shows as Bag 5/30). The 4 items you wear don't count.
• +10 bag slots: buy 10 more slots with $SWEEP, up to 60. 30 → 40 costs 100k, 40 → 50 costs 250k, 50 → 60 costs 500k.
• Full bag? Your chests stay closed until you make room. They are never lost, and Rumble loot keeps adding chests.
• Discard throws an item away for good. There is no reward, and you can't get it back.

Item fusion

Put 3 items of the same rarity into the forge to get 1 item of the next rarity. Every step costs $SWEEP and has its own chance. Items you wear can't go in: unequip them first. Mythic is the top, so mythic items can't be fused.

• Success: the 3 items merge into 1 new item. If all 3 are the same slot (say, 3 hats), you get that slot; otherwise the slot is random. Which of the 4 pieces of gear you get is random too, and so is its signature attribute.
• Fail: 1 of the 3 items is destroyed, the other 2 come back to your bag. The fee is spent.

Every fighter gets loot: better placement, more chests. An equipped companion adds chests and XP. Not just the winner gets something.

• Every fighter also gets +10 XP per Rumble.
• Your equipped companion adds its own chests and XP to every Rumble you fight in, and better chest rarity.
• Fight awards: the four busiest brooms of each fight get +3 chests each: most knockouts, most comebacks, most dodges and most traps. A tie goes to the better placement.
• Loot rolls come from the same seed as the fight, so they can be checked too.

A companion is a little critter that rides along in your one companion slot. Companions come from companion chests (50k $SWEEP) and the week streak. They bring chests and XP from every Rumble you fight in but do not change your fight stats.

Chests and XP: added to your loot of every Rumble you fight in. Rarity boost: chance that a chest from that Rumble rolls one rarity higher when you open it. Mythic: also a 20 % chance to double your whole loot of that Rumble (placement chests, companion chests and XP). Shadow Paw exists only once: the prize of the first broom on level 20.

Fusion

Fuse duplicates into a higher rarity. Fusing companions is free, but it can fail: then half of the companions you put in are lost. Mythic companions cannot be fused into; they only come from chests and special events. Unequip a companion before fusing it.

Stakers get daily quests: they bring XP and item chests and start fresh every day (the Quests tab shows when the next day begins). Rewards land as soon as a quest is done. Find them in My Broom → Quests.

• Daily chest pack: once a day, 5 item chests for 50k $SWEEP.
• Launch quests, once for the whole arena: the first broom on level 5 gets 20 chests, the first on level 10 a mythic companion, and the first on level 20 Shadow Paw, a mythic ninja cat that exists only once. The moment the upgrade ends (or is skipped) counts.
• Quests and the chest pack are for stakers only. Trading volume is read from the explorer and can take a minute to show up.

1. Fighters are locked. When joining closes (60 seconds before the fight), the list of joined fighters, with their class, level, items and companion at that moment, is fixed and hashed.
2. The seed. The hash of the draw block on Injective plus the fighters hash give the Rumble seed. Nobody can pick it.
3. Same seed, same fight. The engine plays the whole Rumble from that seed: every round, the winner and everyone's loot.
4. Shown live, revealed at the end. The fight is computed as soon as the block is in, but the site shows it to everyone at the same moment and publishes the winner and the loot only when it has played out.
5. Verify it yourself. Press Verify on a finished Rumble: your browser reruns the engine and checks the winner.

What happens inside a chest you open (the item and its rarity), companion chests, the week reward and fusion use the server's random roll. Each result is logged, but it is not on-chain.

The fine print

Seed = SHA-256(blockHash : fightersHash). The fighters hash commits to every fighter (address, class, level, stats and equipped companion, sorted by address), the engine version and the settings, and is published before the draw block exists.

Loot comes from the same seed: SHA-256(seed:loot:wallet:n) decides the 30 % chest of the lower half and the mythic double; the fight awards are counted from the fight itself. The companion never changes the fight.

Only stakers with a class who pressed Join for that Rumble and still have the stake in the staking contract, read at the snapshot block, fight. There is no pause after a win: a winner can win the next Rumble too.

There is no exclusion list in the Rumble: every staker stakes exactly the same and fights like anyone, team wallets included. The team can void and redraw a draw; voided draws stay visible on the start page, marked “Redrawn”.
