9 Coins – Extremely Light is a dynamic video slot from Wazdan in which the developer combines a compact engine with the cult Hold the Jackpot mechanic. The game is aimed at those who value instant loading, smooth animation even on low-end devices, and are not willing to sacrifice deep bonus features. Eight years of experience within the Wazdan team can be felt in every detail: from perfectly balanced mathematics to a multi-tier Mystery system with Mini, Minor, Major and Grand jackpots. In this review we will dissect the advantages of the “light” version, evaluate the RTP and volatility, explain how the sticky Cash Infinity feature is triggered, and offer working strategies for hunting the maximum 500× win.
Down to Business: Mechanics, Design, and Technical Profile
Despite the “Extremely Light” label, the slot retains the signature visual style of the 9 Coins series: a 3 × 3 symbol game area, a minimalist fruit palette, and glass reels highlighted with neon. Thanks to compressed assets and optimized scripts, the client size has been cut almost in half compared with the original version, reducing load time to a single second even on mobile internet.
The game offers a stated RTP of 96.14 % and high volatility, meaning rare but hefty payouts. The RNG model has been certified by GLI, and the machine itself is built on the Unity engine—familiar to many HTML5-slot developers. Bets range from 0.10 to 10 credits, making the slot equally comfortable for casual players and high-rollers testing an aggressive Chance Level strategy.
What Genre Does the Slot Belong To?
According to Wazdan’s classification this is a “fixed grid, no-payline” slot: wins are formed not by paylines but by bonus symbols locked in the centre row. Such a structure greatly simplifies perception for newcomers yet leaves room for experimenting with the frequency of special symbols. Key features keep interest high: sticky Cash Infinity icons, instant Cash payouts, and multi-level Mystery prizes. This approach is close to the “coin” slots in land-based casinos, but seasoned with modern infographics and an adaptive interface.
From Spin to Jackpot: Rules and Hidden Nuances
The base session starts in a standard way: spin — wait — result. Yet the real value of spins is revealed when a trio of bonus symbols lands on the middle horizontal row. This exact combination triggers the main Hold the Jackpot round, where the potential for winnings of up to 500× the stake is embedded.
Cash symbols award instant payouts from 1× to 5× the stake. Far more interesting are Cash Infinity: they “stick” and remain on the reels until the end of the subsequent bonus round, increasing the chance of Hold the Jackpot activating. Their nominal value is much higher—between 5× and 10× the stake—which, paired with the sticky mechanic, creates an impressive boost to the bankroll.
After the bonus begins, the player is taken to a clean 3 × 3 grid with the triggering symbols already fixed. You get 3 respins; each new non-empty icon resets the counter back to three. At this stage the cash coins are joined by:
- Mini Jackpot — 10× the stake;
- Minor Jackpot — 20× the stake;
- Major Jackpot — 50× the stake.
There are also surprises: the Collector gathers all current Cash and Cash Infinity values and multiplies the total by a random coefficient of x1–x9. And symbols reveal themselves at the end: a regular Mystery transforms into any bonus icon except Cash Infinity, whereas a Jackpot Mystery guarantees one of the three jackpots.
The round ends when respins are exhausted or the grid is completely filled. In the latter case the Grand Jackpot — 500× stake is triggered and all other amounts are cancelled: the maximum win limit has been reached. If the grid is not completely filled, the player receives the cumulative value of all collected symbols.
The thin line between “almost success” and a fully completed grid makes every spin incredibly tense, and the bet selector (Chance Level) lets you vary bonus frequency without changing coin value. Pro players recommend alternating 25–30 spins on the standard level with 5–10 quick spins on the higher level—this preserves the bankroll balance and increases the chance of landing sticky Cash Infinity in the central line.
The Road to Rewards: Payout Table and Jackpot Tiers
Below is a simplified reference for the main prize icons. Columns show the number of matching symbols, and rows list the name and corresponding stake multiplier.
| Symbol | 3 |
|---|---|
| MAJOR Jackpot | 50× |
| MINOR Jackpot | 20× |
| MINI Jackpot | 10× |
During Hold the Jackpot it is possible to land several jackpots of the same type, so the final multiplier can significantly exceed the base values. Thanks to sticky Cash Infinity, the combination of Mini + Minor + Major is not uncommon, especially during long respin streaks.
Risk-Free Test Drive: Switch On Demo and Train Your Strategy
Demo mode is a free version of the slot with virtual credits. Results are identical to real play because the same RNG controls outcomes, yet no real money can be lost. It is the perfect environment to:
- evaluate the frequency of Cash Infinity drops;
- practice switching Chance Level and bet sizes;
- determine a comfortable bankroll before playing for money.
To launch the demo:
- Open the slot in your desktop or mobile browser.
- Find the Real/Demo toggle under the “Spin” button (usually accompanied by a coin icon).
- Click it and the balance will automatically switch to play credits.
If the button does not activate, use the additional switch in the upper left corner of the control panel—it looks like on the screenshot in most casino clients. If access is blocked by regional restrictions, a VPN will help.
Tip: make at least 200–300 demo spins alternating low and high bets. Such a sample will give a statistically meaningful understanding of volatility and the average length of the Hold the Jackpot round.
Final Verdict and Closing Tips
9 Coins – Extremely Light proves that a “mobile” version does not necessarily have to compromise on the original. Wazdan has smartly optimized graphics while leaving the series’ main advantages untouched: the lively Hold the Jackpot mechanic, sticky Cash Infinity, and a universal bet range. Players get a fair RTP, the ability to choose volatility via Chance Level, and a maximum win of 500× with no hidden limits.
Who is this slot for? Beginners—thanks to the simple trigger conditions and clear payout table; advanced jackpot hunters—for the combination of high multipliers and the rare Collector feature. Mobile gamers will appreciate the loading speed and low data consumption. If you love risk, try the “step bet” strategy (10 spins at the minimum, 5 at the maximum)—it increases the chance of catching Cash Infinity and doesn’t drain the bankroll too quickly.
The main takeaway is simple: 9 Coins – Extremely Light turns every spin into an event where both instant payouts and the adrenaline of chasing the Grand Jackpot are at stake. Play responsibly, test the demo, and let the lightweight format lead you to heavyweight wins!
