A confirmation is the moment the network adds your transaction to a block. Every subsequent block adds one more confirmation and makes the transaction irreversible. Casinos usually credit a deposit after one or two confirmations and may require more for larger amounts.
How long it takes. The time depends on the network, not the casino. In Bitcoin a block appears on average about every ten minutes, so a couple of confirmations means tens of minutes. In Ethereum the block interval is measured in seconds, in Tron a transaction is practically instant, in Litecoin it takes a couple of minutes. A large part of the feeling of a slow casino comes from exactly here: often you are waiting for the network, not the operator. With a withdrawal the casino's own processing time is added, which is an entirely separate number.
If a transaction hangs:
- Too small a network fee on Bitcoin or Ethereum — the transaction sits in the mempool until the fee matches the market. Some wallets allow the fee to be raised afterwards.
- The casino waits for more confirmations when the amount exceeds its threshold. That should be stated in the payment terms; if it is not, that is a shortcoming.
- The wrong network or a missing memo. Then the transaction confirms but the money does not reach the account — support has to intervene and it does not always succeed.
What to check. Copy the transaction ID (txid) immediately after sending: in a block explorer you can see exactly whether you are waiting for the network or the casino, and support will ask for the same ID first. Before a large transfer, send a small test amount. Typical confirmation times and the number of confirmations required are collected in the payments overview, and operator by operator in the reviews.
Why the number of confirmations is a security requirement
One confirmation means the transaction is in a block, but in rare cases a fresh block can be replaced by another one when parts of the network briefly see a different chain. Every new block on top makes reversing the transaction harder. That is why casinos require more confirmations for larger amounts: they do not want to credit money that could still vanish from the chain. For you, the required number of confirmations is the casino's risk threshold, not a delay for its own sake. For background, Ethereum.org: transactions describes how a transaction reaches a block.
Example: how long the wait is
If Bitcoin produces a block roughly every 10 minutes, three required confirmations means about 3 × 10 = 30 minutes. If six were required, it would be about an hour. On Ethereum the block interval is about 12 seconds, so the same three confirmations take around half a minute. That is why a Bitcoin deposit is often slow and one on Ethereum or Solana is fast, even though the casino is the same in both cases. Lightning skips waiting on the chain altogether.
What not to do
- Do not send the same amount again while the transaction is still unconfirmed. An unconfirmed transaction is not lost, and sending twice only doubles the fee and the confusion.
- Do not assume a confirmation means crediting. The casino may run its own checks before updating the balance, and that is a separate step.
- Do not look only at the casino cashier. Check the transaction in a block explorer; you can see the number of confirmations there in real time.
