If you've played a new RTG or SpinLogic release lately, there's a good chance it had a hold and spin feature. Glowing coins lock in place, the respin counter resets, and the screen fills toward a jackpot. It's become one of the most popular bonus mechanics in online slots.
This guide explains how hold and spin slots work, the common variations you'll see, how to read RTP and volatility for these games, and which titles we've reviewed so far. Think of it as the hub for our Hold & Spin game reviews. We'll add every new release here.
What Is a Hold and Spin Slot?
A hold and spin slot is a game with a bonus round where special symbols, usually coins or orbs carrying cash values, stay locked on the reels while the other positions respin.
The basic flow looks like this:
- Trigger — land a set number of special symbols (often six or more) in the base game.
- Lock — those symbols stick in place, and the rest of the grid clears.
- Respin — you get a set number of respins, typically three.
- Reset — each new special symbol that lands locks in place and resets the respin counter.
- Finish — the round ends when you run out of respins or fill the grid. You're paid the total of all the values on screen.
Filling every position usually awards the game's top fixed jackpot.
Common Hold and Spin Features
Modern RTG and SpinLogic games build on the basic mechanic with extra symbols and modifiers.
| Feature | What it does |
|---|---|
| Cash / coin symbols | Carry a cash value, shown as a multiple of your bet |
| Jackpot symbols | Award a fixed jackpot (often labelled Mini, Minor, Major, Grand) |
| Collector symbols | Gather the values of other coins on screen into one prize |
| Multipliers | Multiply individual coin values or the whole round total |
| Multiple modes | Different bonus versions depending on which symbols triggered it |
| Buy Feature | Lets you pay a fixed price to enter the bonus round directly |
Example: Crimson Castle
RTG's Halloween release, Crimson Castle, pairs Golden Coins with a Moon collector symbol, random multipliers and fixed jackpots. It also offers a Buy Feature and full mobile play.
Example: Treasure Sparks
SpinLogic's Treasure Sparks features three Hold & Spin modes, jackpots and a Buy Feature, with a 95% RTP and medium volatility.
RTP and Volatility in Hold and Spin Slots
RTP (return to player) is the theoretical percentage of all wagers a slot pays back over millions of spins. A 95% RTP means $95 returned per $100 wagered on average, over the very long run. It tells you nothing about any single session.
Volatility describes how wins are spread out:
- Low volatility — frequent small wins.
- Medium volatility — a balance of regular wins and occasional bigger hits.
- High volatility — long dry spells broken by large wins.
Hold and spin games often pack much of their value into the bonus round. That means base-game play can feel quiet between triggers, especially on higher-volatility titles. Plan your session budget with that in mind. Our slot strategies for 2026 covers bankroll basics in more depth.
Is the Buy Feature Worth It?
The Buy Feature lets you skip the base game and pay a set price, often a large multiple of your bet, to go straight into the bonus.
Pros: instant access to the most exciting part of the game.
Cons: it's expensive, it burns through a budget quickly, and the bonus can still pay less than you spent.
If you use it, decide in advance how many buys fit your budget and stop there. Also note that some casinos restrict Buy Feature play while a bonus is active. Check the terms and our wagering requirements guide.

Frequently Asked Questions
How do hold and spin slots work?
You trigger the bonus by landing a set number of special symbols. They lock in place and you receive a few respins, usually three. Each new special symbol locks and resets the respins. When the respins run out, you win the total value of all locked symbols.
Can you win a jackpot on a hold and spin slot?
Yes. Most hold and spin slots include fixed jackpot symbols, and filling the entire grid typically awards the top jackpot. Jackpot values and odds vary by game.
What is a collector symbol?
A collector symbol gathers the values of other coins on the screen and adds them together into a single prize. Crimson Castle's Moon symbol is one example.
Are hold and spin slots high volatility?
It varies by game. Treasure Sparks, for example, is medium volatility. Because many hold and spin games pack their biggest wins into the bonus round, base-game play can feel slower between triggers.
The Bottom Line
Hold and spin slots are easy to learn and built around one exciting moment: watching the grid fill up. Learn the specific symbols in each game, check the RTP and volatility, and set a budget, especially if you use the Buy Feature.
