Coin-lock slots: how the Hold and Win bonus plays out
Hold and Win, also called coin lock, is a bonus format in which special coin symbols freeze in place and you get a limited number of respins to add more. In our slots the round starts when six or more coins sit on the grid at once, and it gives you three respins. The format is popular because it is easy to follow: you can see what has been collected. Below: how it works, why it does not simply pay more often than other bonuses, and how three of our games build it.

How a coin-lock round works
Coins with values appear on the normal reels. When enough of them land (six or more in our games), a special round begins. The coins stay where they are, the other cells are empty and spin again. You get three respins; if a new coin lands in a respin, it locks too. The total of the round is the sum of the values of all coins on the grid.
Unlike classic free spins there are no paylines or combinations here: the value comes from how many coins you have and what each is worth. That makes the round easy for a newcomer to read, but it is still part of the slot's maths and every value is drawn by the server.
What to expect from frequency
Our bonus slots are high volatility. A typical hit rate in the base game is 18-26% of spins, but the coin round itself arrives noticeably less often, and gaps between entries can be long. Sometimes you enter the round and close it with a handful of small coins; sometimes one or two big coins make the whole result.
A nearly full grid looks spectacular, but most rounds never fill it. Do not read a near miss as being close to success: by the fifth or tenth empty respin the chance on each one is the same as before. For more on the spread of results, read about volatility.
Our coin-lock slots
Rainbow Pots: six or more coins start three respins, and the game is built around a rainbow multiplier ladder, so the format is paired with a multiplier mechanic.
Sun of Ra: the same trigger, six or more coins and three respins. If you want the direct version of this format without extra layers, start here.
Raccoon Riches: the bonus is a gold-sack coin round, a different take on the format, so check the rules for the exact round order and respin count.
What to check in the info panel
Open the rules and look for:
- How many coins are needed to trigger and how many respins you get.
- What happens when a new coin lands: whether the respin counter stays or resets.
- Theoretical RTP and Max win per round: each game has its own figures.
- Whether there is a buy option and what it costs: see the page on bonus buy slots.
Keeping expectations realistic
First, a coin round does not guarantee a big sum. Many entries finish with less than a few normal spins cost. Second, entering the round does not by itself pay back a run of empty spins. Third, multipliers, as in Rainbow Pots, only boost the result when there is something to multiply.
To see how multipliers work in other formats, visit the page on multiplier slots.
Bankroll and demo
For high volatility slots it makes sense to choose a stake that lets you survive a long run without the bonus. Play the game in demo first: a guest plays demo only, on a $10,000 balance that can be topped up for free. See whether you like the rhythm of waiting before you play for money.
For the meaning of return to player, see the RTP guide. You must be 18+; play responsibly and never chase losses.
Frequently asked questions
What is Hold and Win?
A bonus format where coin symbols lock on the grid and you get a limited number of respins to add more. The round total is the sum of all coin values. In our games the round starts with six or more coins.
How many respins do our slots give?
In Rainbow Pots and Sun of Ra, six or more coins start three respins. Raccoon Riches uses a gold-sack coin round. Check the game's info panel for the full rules.
How often does the coin round trigger?
Noticeably less often than a base game win: in bonus slots wins land on 18-26% of spins, and the bonus is rarer still. Long gaps between entries are normal for high volatility.
Can I influence the respins?
No. The coins are drawn by the random number generator on the server and the browser only shows the result. Neither the timing of your click nor the size of your bet changes the chance of a coin.
What RTP do Hold and Win slots have?
Each game has its own. The operator sets RTP per slot, and the Theoretical RTP in the game's info panel is the one that applies. There is no single figure for the genre.
