20 Coins – Hold the Jackpot – Cash Infinity is an unconventional online slot with 20 independent reels on a 4 × 5 grid. There are no familiar paylines or pictures in the base game: all potential is locked inside the Hold the Jackpot™ bonus round, so every spin acts as a preparation for the main event.

Visually, the slot is wrapped in a gleaming gold theme, and the smooth animations highlight the appearance of special symbols. The HTML5 engine guarantees equally fluid performance on desktop and mobile devices, supporting Turbo Spin mode and Full-HD graphics. Even with a weak connection the interface compresses textures without losing sharpness, so the coins keep their sparkle.

The soundtrack is built on the principle of adaptive audio: while the reels spin idly, a relaxing ambient plays, but when a sticky symbol lands a muted gong is triggered. In the bonus game the deep drumbeats intensify with every respin, syncing with the player’s heartbeat — it adds drama and makes each win emotionally tangible.

What type of slot it is

The game belongs to the collect & win genre with built-in fixed jackpots. The player can manually switch volatility (Low — Double Extreme) and, if desired, buy the bonus round via the Buy Feature button. The stated RTP is 96.14 %, and the random number generator is certified by GLI and eCOGRA. Five Volatility Level™ settings let you adapt risk to bankroll: Low delivers frequent but small prizes; Extreme offers rare yet impressive payouts.

The cost of the Buy Feature depends on the selected volatility level: on High the price is 60× the stake, whereas on Double Extreme it is 80×. Despite the higher ticket, the Double Extreme math includes an increased chance of hitting the Major jackpot, which attracts hunters for big multipliers.

Game rules: when every coin counts

The essence is simple — four coins open the doors to Hold the Jackpot™

• 4 × 5 grid actually contains 20 mini-reels, each with its own stop line and independent animation.
• In the base game only coins, Mystery icons and sticky symbols appear; there are no ordinary “pictures”.
• Four bonus symbols in a row in the central column trigger Hold the Jackpot™; the column is framed in gold so you don’t lose track of progress.
• Payouts are awarded only after the bonus; the base spins serve as a “selection” of symbols for activation.

Imagine that the first three coins have already occupied their places in the centre, leaving one empty cell. Every subsequent spin turns into a small lottery where the trigger chance feels almost physical. This mechanic holds attention better than traditional paylines because the player sees the tangible “shortage” before the bonus.

If a sticky Mystery is stuck in the centre, the probability of launching the bonus is even higher — on average 1 in 30 instead of 1 in 70. That’s why many players purposely slow down autospin when at least one sticky icon appears in the centre: the visual anticipation intensifies, and with it the pleasure.

Paytable: how much the coins and jackpots are worth

Check the odds before you spin

Symbol	1	2	3	4	5+
Cash coin	1×	2×	3×	4×	5×
CASH INFINITY™	5×	6×	7×	8×	10×
Jackpot Mini	—				10×
Jackpot Minor	—				20×
Jackpot Major	—				50×

Cash coins award 1×-5× each, while CASH INFINITY™ symbols lock in place and pay 5×-10× at the end of the bonus. With five CASH INFINITY™ worth 10× each, the guaranteed prize is 50× even if every other cell is empty. Mini, Minor and Major symbols grant fixed multipliers of 10×, 20× and 50×; you can land them several times in one round, allowing you to combine, say, three Minor and one Major for a hefty sum.

For clarity: a €2 stake and two Major jackpots yield €200 (2 € × 50 × 2). Add a Collector with a 5× multiplier and the final win rises to €1 000. These cascading scenarios make the game explosive on High volatility.

Signature features: two ways to glue luck to the reels

STICKY TO INFINITY™ and CASH INFINITY™ in action

STICKY TO INFINITY™

• Mystery and Jackpot Mystery symbols can “stick” and stay until the end of the next bonus.
• A sticky symbol in the centre increases the chance of activating Hold the Jackpot™ from ~1.4 % to ~3 % on each spin.
• If you change the stake or volatility the symbols disappear, but they return if you revert to the previous settings.
• Sticky icons are highlighted with a wax-like sheen so they can’t be confused with regular symbols.

CASH INFINITY™

• CASH INFINITY™ carries 5×-10× and locks on the reels until the bonus.
• Payment happens only after the round ends, creating a “reserve” win even on a modest grid.
• Up to five such symbols can be present simultaneously in the base mode.
• If CASH INFINITY™ lands in the centre, the bonus probability doubles, so seasoned players avoid changing the stake after such an event.

The combination of Sticky and CASH INFINITY™ forms a three-stage anticipation chain: landing, bonus activation, Mystery reveal. Thanks to this, the game cycle feels rich even without traditional free-spin rounds.

Strategy: how to improve your chances for a big hit

From bankroll to jackpot — a step-by-step plan

1. Choose the right volatility. Low triggers the bonus more often, Extreme less frequently but more expensively; Double Extreme is designed for short aggressive sessions.
2. Preserve your balance. Keep the stake within 1-2 % of the bankroll per spin; for a €100 bankroll that is €1-2.
3. Lock in sticky symbols. Do not change the stake if a Sticky or CASH INFINITY™ appears in the centre — otherwise the accumulated bonus chance will vanish.
4. Use the Buy Feature consciously. First make 30-40 normal spins: a random activation is possible without extra costs.
5. Control your goal. A full screen awards a Grand jackpot = 1500×; every strategy should aim to collect 20 symbols.

Additionally set a “soft” stop-loss (for example, −30 % of the initial bankroll) and a “hard” profit target (for example, +100 %). Such discipline protects against emotional overspin, especially on Extreme levels.

Bonus game: the heart of the slot

Hold the Jackpot™ — three spins to break the bank

What is a “bonus game” in slots?

A bonus is a separate mode with special rules and increased payouts. In 20 Coins it is three respins with symbols locked in place; each new coin resets the counter to three. The mechanic is close to popular hold & spin games but expanded with collective jackpots and a Collector multiplier.

How Hold the Jackpot™ works

• Start: 3 respins, all active bonus icons are locked.
• Counter reset: every new bonus symbol brings the respins back to 3.
• Finish: the round ends when respins run out or all 20 cells are filled.
• Payouts:
  • Cash — 1×-5×
  • CASH INFINITY™ — 5×-10× (paid at the end)
  • Mini/Minor/Major — 10×/20×/50×
  • Collector multiplies the sum of Cash icons up to 20×
  • Mystery transforms into any bonus symbol except CASH INFINITY™
  • Jackpot Mystery — guaranteed Mini, Minor or Major
• Grand jackpot: 20 bonus symbols pay 1500× the stake.

Collector becomes the key figure: if 40× in coins have accumulated on the field and a Collector with a 10× multiplier appears, the final boost will be 400×. Such a catalyst can turn a modest bonus into an epic win.

Extreme and Double Extreme volatility

You can purchase the bonus on high volatility via the Buy Feature. The rules are the same, but large multipliers appear noticeably more often, Cash coins less frequently. The Double Extreme math targets 200×+ prizes, and the variance demands patience and a solid bankroll.

Demo mode: practice without risk

Free training before real stakes

Demo mode launches the slot with virtual credits. It is a safe ground for studying volatility, bonus frequency and sticky symbol behaviour. Use a spin spreadsheet: run 200 spins on Low, 200 on High and compare the Hold the Jackpot™ frequency. The difference will show which style suits you.

How to enable

1. Open the slot in a supported casino and choose “Demo” or “Play for Fun”.
2. If the demo does not start, toggle the switch next to Spin or refresh the page — sometimes the browser blocks a pop-up window.

Remember that progress and sticky symbols in demo do not carry over to real mode: when you switch to money a new session starts from scratch.

Conclusion: choose your strategy and hold the coins tight
