Real premium currency. Buy it, spend it, send it, take it with you.
Gold in Ship Busters is INVO currency. It is your own gold balance on your INVO ID, not locked inside one game. Spend it at the harbor market, send it to another captain by phone number, or carry it across to another supported INVO game, where it arrives as that game's own currency. Every move is approved with a passkey.

The technology
Ship Busters is developed by Invo Tech Inc., the company behind INVO, and runs on INVO, a network that lets players carry premium currency between games and platforms. In Ship Busters, that currency is gold.
That is why the Steam store page lists Requires 3rd-Party Account: INVO. Your INVO ID is simply your Ship Busters sign-in with an email on it. Learn more about INVO.
Getting gold
Gold is the one currency the game never hands out. No battle, reward track, Voyage or drop ever pays it. You get gold two ways: buy it, or have another player send it to you. Silver and energy are what you earn by sailing.
Pick a pack on the Shop's gold shelf and pay from your Steam Wallet. The price list comes from Steam.
INVO's secure checkout opens inside the game, so you never leave the sea to buy. Ship Busters never sees or stores your card number. Play free from Oct 29.
The phone versions run the same game and the same INVO ID, so your gold balance is the same gold wherever you sign in.
10 gold to the US dollar at every tier
Gold is never discounted: every tier is the same rate, so a bigger pack is a convenience, not a better deal. On Steam, packs and prices are set by Steam and paid in your Steam Wallet currency.
You need an account with an email to buy. INVO finds your gold balance by your email, and your receipts go there too. Try to buy without one and the game asks you to sign in first, then opens the checkout straight after, so the gold is never stranded on a single device.
Spending gold
Every shelf in the Shop prices in gold, with the price set on the server. These are the prices in the game today.
More battles before you wait. Energy is bought with gold only.
The coin that levels your gear. Also earned by fighting.
A single 3-star piece for the slot you choose: hull, mast, sail, gun, ram or keel. A flat price, with no crates and no odds.
Every ship arrives whole and ready to sail, fitted with a full six-piece 7-star rig. Ten ships are on the shelf, from the Rust Bucket at 60 gold to the Capital Ship at 200 gold.
Gear sets for the fleet you already have, on the Shop's This Week shelf.
99 gold buys 30 days of standing, on every build. Buy again while it is live to extend it, up to 90 days ahead. A monthly charter that renews automatically is also offered. While you hold it:
Charter perks never apply in duels. When a charter ends the perks stop, and nothing you own is taken away.
Free to play. The whole game is free. In-game purchases are optional, and nothing sold in the shop is needed to finish the campaign or win a duel.
From the Ship Busters Steam store pageTransfers
This is what makes INVO gold different. Open TRANSFERS on the top bar (or Gold transfers in Captain's papers), pick where the gold is going, and send it. Gold is addressed to a phone number, so the person on the other end does not even need to play Ship Busters yet.
Ship BustersAnother captain
Ship BustersAnother supported INVO game
Pick Ship Busters or another supported INVO game. Games not yet open for transfers are greyed out and cannot be picked.
Choose the country, type the number the way you say it, and enter how much gold. Limits are checked right there.
The amount is reserved for ten minutes. Nothing has moved yet; it just leaves your available balance while you confirm.
Fingerprint, face or device PIN. This is the step that actually spends it. On Steam you approve on your phone.
The gold waits with INVO until the other side collects it. Sent is not collected, and the Activity tab says which.
The recipient opens Collect and takes it with their own passkey. No codes are passed around.
The reservation lapses on its own. Nothing is spent and the gold comes back. Activity shows it as "never confirmed, so nothing was spent".
The game shows a QR code and a short code. Approve on your phone and the transfer finishes on your PC or Mac. See how.
Some moves pause for a review or an approval. That is not a failure: the gold is held safe and the move shows under Activity until it settles.
Where it is going, to whom, and how much. Shows your balance and anything currently held against a transfer you have not confirmed.
Gold sent to you, each with a one-tap passkey Collect. On a device with no passkey yet, it offers Enrol this device first.
Moves still waiting on your approval, moves on their way, and finished ones. A count on the TRANSFERS button tells you when something needs you.
Steam and desktop
Purchases and transfers both work in the full Steam game. A passkey is tied to a website, and the desktop game window has none to tie it to, so the passkey step moves to your phone, where your passkey already lives.
On Steam there is also an Open it in me browser button, if your computer's browser already has your passkey. The first time a new phone is used, the game asks you, on the game screen, to confirm the phone is yours by matching a short code. Answer no and nothing leaves your purse. Collecting gold on Steam works the same way.
Safety
Gold is real money, so every move out, and every collection in, needs proof that only you can give.
Sending and collecting are both approved with a passkey: a credential that stays on your device, unlocked with your fingerprint, face or device PIN. It cannot be phished, read off a lock screen or captured with a SIM swap. There are no texted codes for moving gold.
Naming an amount only reserves it. Nothing moves until you approve, and that step is never skipped or remembered. A stolen session can start a move; only the device with your passkey can finish one.
Setting up the first passkey on a device needs a one-time code, sent to both the phone and the email on your account. That code creates a passkey; it never moves gold.
When a desktop approval is picked up by a phone for the first time, the game asks you on the game screen to confirm it by matching a code. A stranger who photographs the QR cannot press yes on your screen. The approval code itself never leaves our server.
Lost your passkey? Recover it from the passkey screen. A newly replaced passkey can collect straight away but cannot send gold for 24 hours, and the game says so before you start, not when you try to pay a friend.
INVO finds your gold balance by the email your sign-in proves, not by anything typed into a form. Your phone number is only an address for gold, never a password, and one number belongs to one captain.
Sometimes INVO pauses a move. In every case the gold is held safe and the move stays under Activity until it settles.
Before you start
Open Captain's papers and choose Purchase history. It lists gold bought, gold spent and anything refunded, with the date, the price in US dollars where there is one, and the gold amount. Transfers have their own record under the Activity tab.
A purchase can take a moment to land after checkout closes. If it is still missing, or a transfer looks stuck, email support@ourinvo.com with your Captain ID, the email on your account, your platform, roughly when it happened and the amount.

Questions
Gold is the premium currency of Ship Busters. It runs on INVO, the premium currency network from Invo Tech Inc., the developer of Ship Busters, and is kept as a gold balance on your INVO ID, tied to the email on your Ship Busters account. Because it lives on INVO, gold can be bought, spent in the shop, sent to another player, or moved to another supported INVO game.
No. Gold is the only currency in Ship Busters that is never awarded by play. No battle, reward track, Voyage or drop pays gold. You get gold by buying it or by receiving a transfer from another player. Silver and energy are earned by playing.
In the full game on Steam, open the Shop and pick a gold pack. You pay with your Steam Wallet: on Windows Steam shows its own confirmation over the game, and on a Mac Steam's checkout opens in a window of its own. Gold is added to your gold balance once Steam confirms the payment. Prices on Steam come from Steam.
Yes. Choose TRANSFERS on the top bar, pick Ship Busters as the destination, enter your friend's phone number and the amount, then approve with your passkey. Your friend collects it with their own passkey. The person you send to does not need to play Ship Busters yet.
Yes. The Send tab lists the supported INVO games that gold can go to, each with the currency it arrives as. Pick a game and the gold crosses over as that game's own currency. Your own phone number is fine here, which is how you move your own gold to your own account in another supported INVO game. Moves to another supported INVO game carry an INVO fee, and the form shows each game's limits before you commit.
Starting a transfer only reserves the gold. Nothing moves until you approve it. A reservation lasts ten minutes; if it is not approved in that time it lapses, nothing is spent, and the gold comes back to you on its own. The Activity tab shows it as never confirmed.
The desktop game window cannot hold a passkey, so you approve on your phone instead. The game shows a QR code and a short code. Scan the QR with your phone, or open the address shown and type the code, then approve with your fingerprint or face. The game waits and finishes the transfer by itself. On Steam you can also open the approval in your computer's browser.
Use Lost or replaced yer passkey? on the passkey screen to recover and make a new passkey. For your safety, a newly replaced passkey can collect gold straight away but cannot send gold for 24 hours. If you still have the old device, use that instead.
No. The free Next Fest demo has no shop, no purchases, no transfers and no account screens. Gold is part of the full game.
No. Ship Busters is free to play. In-game purchases are optional, and nothing sold in the shop is needed to finish the campaign or win a duel.
Open Captain's papers and choose Purchase history. It lists gold bought, gold spent and anything refunded on your account. For help with a purchase or a transfer, email support@ourinvo.com.
