TL;DR: xWays is a symbol-expansion mechanic developed by No Limit City. When an xWays symbol lands on a reel, it expands to between 2 and 4 (or more) identical symbols, multiplying the number of active ways-to-win on that spin — sometimes up to 200,704. It doesn't change the RTP, but it dramatically increases variance and peak win potential.
What Is the xWays Mechanic, Exactly?
xWays is a proprietary mechanic trademarked by No Limit City (NLC), the Swedish developer behind high-volatility titles like Deadwood, Tombstone, and Mental. The name refers to the way it expands active paylines — or more precisely, ways to win — within a single spin.
Here's the core mechanic in plain terms:
- An xWays symbol lands on a reel during a spin.
- That symbol expands vertically, revealing 2, 3, or 4 identical standard symbols in its place.
- Because ways-to-win slots count every possible symbol combination across adjacent reels, adding rows to one reel multiplies the total ways-to-win across the board.
- The result: a single spin can shift from a standard 3,125-way grid to tens of thousands of active win lines.
It's not magic. It's combinatorics. And the numbers get large fast.
The Ways-to-Win Math Behind xWays
To understand why xWays creates such dramatic swings, you need to understand how ways-to-win slots are calculated. In a 5-reel, 3-row slot, the total ways-to-win = 3 × 3 × 3 × 3 × 3 = 243 ways. Expand that to 4 rows per reel and you get 4⁵ = 1,024 ways. Mix heights across reels and the numbers compound.
xWays slots like xBomb and Tombstone R.I.P. push this into the hundreds of thousands:
| Reel Heights (rows per reel) | Ways to Win |
|---|---|
| 3-3-3-3-3 (base) | 243 |
| 4-4-4-4-4 | 1,024 |
| 5-5-5-5-5 | 3,125 |
| 6-6-6-6-6 | 7,776 |
| 7-7-7-7-7 | 16,807 |
| 8-8-8-8-8 | 32,768 |
| Variable (max in NLC titles) | Up to 200,704 |
The max of 200,704 ways is what NLC achieves in titles where multiple xWays symbols land simultaneously across all five reels in a free-spin feature. Each additional row added to any reel multiplies the total — that's exponential growth from a simple symbol expansion.
The volatility implication is direct: most spins with xWays symbols land on lower reel heights, generating ordinary wins. Occasionally, multiple xWays symbols align at maximum expansion during a feature — and that's where the game's peak win (often 5,000–10,000× stake) lives. High variance, not high frequency.
Which Slots Use the xWays Mechanic?
xWays is exclusive to No Limit City's IP, but it appears in a growing catalogue — often combined with NLC's other proprietary mechanics like xBomb (exploding wild that multiplies), xNudge (wild that nudges to full reel with multiplier), and xSplit.
Key titles to know:
- Tombstone R.I.P. — xWays + xNudge wilds; RTP 96.08%; extreme volatility (NLC rates it 10/10)
- Deadwood — xWays + xNudge; RTP 96.03%; 5,000× max win
- Mental — xWays + xBomb; RTP 96.08%; 46,285× theoretical max
- Infectious 5 xWays — team-play format with five linked slots; RTP 96.06%
- Pixies vs Pirates — entry-level xWays; lower volatility than core NLC titles
All published RTPs above are sourced from No Limit City's official game sheets and confirmed by independent audit — NLC titles are tested under MGA and UKGC licensing frameworks before release.
xWays vs Standard Ways-to-Win Slots: What Actually Changes
The RTP doesn't change. That's important to say clearly. An xWays slot with a published RTP of 96.06% will return approximately €96.06 per €100 wagered over millions of spins — same as any other ways-to-win slot with that RTP.
What does change is where in the distribution that return sits.
In a low-volatility slot, returns cluster around small, frequent wins — you might get 50 small hits in 100 spins and a moderate bonus round. In a high-xWays slot, you might have 95 dead spins, one moderate bonus, and one session where the xWays align at max expansion and the game pays 2,000× in a single free-spin cycle.
Same long-run RTP. Radically different session experience.
For advantage players, this matters in one specific way: wagering requirements on bonuses. A 96.06% RTP means the expected cost of clearing a 35× wagering requirement on a €100 bonus is approximately €(35 × 100 × 0.0394) = €137.90 in expected losses before accounting for the bonus itself. That's the honest EV math every bonus player should run before picking their clearing slot.
Playing a 92% RTP slot on that same wager would cost you roughly €(35 × 100 × 0.08) = €280 in expected losses. The RTP choice is the real edge — and it's a published number casinos almost never advertise.

How xWays Combines with Other NLC Mechanics
No Limit City's real innovation isn't xWays alone — it's the mechanic stacking. Understanding the combinations helps you read a paytable before committing real money.
xWays + xNudge: An xNudge wild nudges to fill an entire reel and carries a multiplier that increases by 1 for each nudge step. If it lands alongside an xWays symbol, the expanded ways grid gets hit with the multiplier simultaneously. This is the core of Deadwood's peak-win engine.
xWays + xBomb: The xBomb explodes adjacent symbols (removing lower-pays) and multiplies the win. On the expanded grid created by xWays, the bomb's multiplier applies to a much larger ways count — compounding the effect.
xWays + xSplit: xSplit duplicates a symbol across two rows. Combined with xWays, this can stack extra rows on top of an already-expanded reel, pushing ways-to-win counts toward their ceiling faster.
Knowing which combination is active in the base game vs. the feature changes how you read the volatility profile — and how aggressively you want to size bets relative to your bankroll.
Bankroll Sizing for xWays Slots: The Honest Math
High xWays titles are legitimately some of the most volatile games in any casino lobby. Playing them without a clear bankroll plan is how most players bust before they ever see a meaningful free-spin round.
A practical rule used by advantage players:
- Minimum session bankroll: 100× your chosen stake. For a €1 spin, bring €100 to the session.
- Realistic bankroll for meaningful feature exposure: 200–400× stake. At 400 spins per hour, a 200× bankroll gives you roughly 30 minutes of base-game exposure at average hit frequency.
- Stop-loss discipline: Set a hard floor — many advantage players exit at 50% drawdown and re-evaluate rather than chasing in a cold session.
Variance is real. The edge in xWays slots is in understanding when to play them (during wagering-requirement clearance on a high-RTP session, or with a +EV bonus attached) — not in assuming the expansion feature will trigger on demand.
Responsible-gambling note: xWays mechanics increase peak-win potential but do not alter the house edge. Always play within a pre-set session budget.
Finding xWays Slots Running Above Baseline RTP Right Now
Published RTP is the long-run theoretical return. In any given session window, live RTP data — actual payout rates across real spins at a casino's live instance of a slot — can run above or below that baseline. Spotting the games currently paying above baseline is the move advantage players make before they open a slot.
Doing this manually means checking hundreds of game instances across dozens of casinos in real time. Nobody has that bandwidth.
Slotio AI scans that live RTP data for you — flagging the xWays titles and other high-volatility slots that are running above their baseline right now, so you can play the ones already paying instead of flying blind.
Frequently Asked Questions
Does the xWays mechanic improve the RTP of a slot?
No. xWays does not change the published RTP. A Tombstone R.I.P. spin at 96.08% RTP returns the same long-run percentage with or without an xWays symbol landing. The mechanic shifts variance — concentrating returns into larger, rarer wins — but the mathematical house edge stays fixed.
Which slot first introduced the xWays mechanic?
No Limit City introduced xWays in Tombstone (2019), the predecessor to Tombstone R.I.P. The mechanic was refined and combined with xNudge wilds in subsequent titles, becoming the signature feature of NLC's high-volatility catalogue.
Can xWays symbols appear in the base game or only in free spins?
It depends on the title. In most NLC games, xWays symbols appear in both the base game and the free-spin feature, but their frequency and expansion range are often enhanced during bonus rounds — which is why the feature is where peak wins occur.
What is the maximum ways-to-win an xWays slot can reach?
No Limit City's most complex titles reach up to 200,704 ways to win when multiple xWays symbols land at maximum expansion simultaneously during a feature. This requires all five reels to expand to their maximum height in the same spin.
Are xWays slots worth playing for bonus wagering clearance?
Yes — if the title has a published RTP of 96%+. The higher the RTP, the lower your expected cost to clear a wagering requirement. Check whether the casino's bonus terms restrict high-volatility or NLC titles before choosing your clearing slot, as some operators explicitly exclude them.
How is xWays different from Megaways?
Megaways (BTG) randomises the number of symbols on each reel every spin — up to 117,649 ways — using a licensed mechanic now used by dozens of developers. xWays is NLC-exclusive and works differently: specific xWays symbols expand individual reels on landing, rather than every reel randomising its height on every spin. Both expand ways-to-win; the trigger mechanism and ownership are distinct.
