Slot Glossary
34 terms covering Only Match's Cluster Pays engine, Cascading Wins, persistent Match Multiplier, the Only Match Bonus, and the path to 8,200x.
Adjacent Cluster
Only Match's win mechanic. Five or more identical gems touching horizontally or vertically form a cluster. Diagonal connections don't count, only horizontal and vertical neighbours. The bigger the cluster, the larger the payout per gem.
Autoplay
Spin the reels automatically for a set number of rounds on Only Match. Useful for grinding the 1-in-220 scatter trigger that opens the Only Match Bonus. Optional stop conditions include stop on bonus trigger, stop on big cluster win, or stop on multiplier reaching x5.
Base Game
Standard play before the Only Match Bonus triggers. Only Match's base game runs cluster pays on the 6x5 grid with a Match Multiplier that ticks up x1 per cascade and resets when the chain dies. Medium-High volatility produces frequent small clusters.
Bonus Buy
Only Match doesn't offer a traditional bonus buy. 100HP Gaming kept the math model honest — no buy bonus, no gimmicks, just chain length carrying the variance. Players must wait for natural scatter triggers (~1 in 220 base spins).
Cascading Wins
Only Match's core engine. After a winning cluster pays, those gems vanish and the gems above slide down. Fresh gems drop into the empty slots from the top. The grid re-evaluates: if new clusters formed, they pay and cascade again. There's no cap on cascade length.
Cluster Pays
Only Match uses Cluster Pays — not paylines. Five or more matching gems touching horizontally or vertically anywhere on the 6x5 grid form a cluster and pay out. Bigger clusters pay disproportionately more — a 12-gem cluster pays substantially more than two separate 6-gem clusters.
Dead Spin
A spin returning nothing. Only Match's medium-high volatility produces dead spins around 68% of the time at base. The Cascading Wins mechanic means many spins start dead but become winners after one or two cascades — what looked like a dead spin pre-cascade becomes a multi-cluster chain.
Feature Trigger Rate
How often the Only Match Bonus activates on Only Match. Natural trigger from 4 scatters: ~1 in 220 base spins. Retrigger from 3 scatters in bonus: ~14%. Bonus rounds reaching x20+ multiplier: ~1 in 25 triggers.
Free Spins
Only Match's Only Match Bonus is the free-spins equivalent. Awards 12 free spins where the Match Multiplier behaves differently — it grows with every cascade and never resets between spins or chains. By spin 8 with steady cluster activity, the meter often sits in the x12-x20 range.
Hit Frequency
How often Only Match produces a winning cluster. Hit rate sits around 32% — about 1 in 3 spins pays something. Standard for medium-high-volatility cluster designs. Cascading Wins effectively boost hit frequency because chains regularly produce 2-3 separate cluster payouts from a single spin.
Match Multiplier
Only Match's headline mechanic. A persistent meter on the side of the grid tracks chain length. First cluster pays at x1. Second cascade applies x2 to the next cluster. Third cascade x3, and so on. In the base game the meter resets the moment a cascade fails to produce new clusters.
Max Win
The absolute maximum a slot can pay on a single round. Only Match caps at 8,200x. The path runs through a long bonus run with the multiplier locked high — typically deep cascade chains in Only Match Bonus where the persistent multiplier reaches x30+ and lands on a 15+ gem cluster.
Max Win Cap
Once Only Match hits 8,200x, the round ends immediately. The 8,200x cap is generous for the cluster category — most cluster slots cap at 5,000x. The persistent-multiplier bonus mechanic is what justifies the higher peak, since the multiplier compounds without resetting through the entire 12-spin round.
Megaways
A Big Time Gaming licensed mechanic with up to 117,649 ways to win. Only Match doesn't use Megaways — it uses cluster pays on a 6x5 grid. 100HP Gaming focuses on cluster designs rather than ways-based formats.
Multiplier
A value that multiplies your win. Only Match's Match Multiplier ticks up by +1x per cascade. In base game it resets when the chain dies. In the Only Match Bonus it persists across the entire 12-spin round — never resets between cascades or spins. That's where the variance lives.
Only Match Bonus
Only Match's flagship feature. Triggered by 4+ scatter gems anywhere on the grid. Awards 12 free spins. The Match Multiplier behaves differently throughout the round — grows with every cascade and never resets between spins or chains. Three additional scatters during the bonus retrigger 4 more spins.
Paylines
Only Match doesn't use paylines — it uses Cluster Pays. Wins resolve through clusters of 5+ matching gems touching horizontally or vertically. The 6x5 layout produces up to 30 cluster positions per spin with no fixed line structure.
Paytable
The reference chart showing each gem's cluster payout. Access through the game's info menu. Only Match's premium gems pay the most: 5-cluster pays 1x, 8-cluster pays 4x, 12+ pays 25x. Mid gems pay 0.5x to 12x. Low gems cap near 5x at 12+ symbols.
Persistent Multiplier
Only Match's defining bonus mechanic. During Only Match Bonus, the Match Multiplier never resets between spins or cascades. Spin 1 might end with x4. Spin 2 picks up at x4 and builds higher. By spin 8, the meter often sits in the x12-x20 range. That's where the 8,200x max win lives.
RNG (Random Number Generator)
The cryptographic algorithm determining every spin outcome. 100HP Gaming uses certified RNGs — independently audited for fairness. Each spin in Only Match is independent of the last; previous cascade chains or multiplier values have zero influence on future spins.
RTP (Return to Player)
The theoretical percentage of wagered money a slot returns over millions of spins. Only Match runs at 96.45% — above the 96% industry standard. Some operators may run 94.50% or 92.10% versions — always verify the exact percentage in the game info screen before spinning.
Scatter
A special symbol triggering bonus features regardless of position. Only Match's scatter is the gem icon designated as the bonus trigger. Land 4+ scatters anywhere on the grid in a single spin (or post-cascade) for 12 free spins of Only Match Bonus.
Session Variance
The gap between actual results and theoretical RTP. Only Match has 96.45% RTP, but a 200-spin session can return 30% to 250% of your wager. Medium-High volatility means deeper swings than low-vol slots — sessions tend to swing more dramatically based on whether the bonus triggers.
Sticky Wild
A wild symbol that stays in place across multiple spins. Only Match doesn't use sticky wilds — its persistence mechanic lives in the Match Multiplier itself. The multiplier sticks across the entire bonus round, providing the equivalent of compounding wild value through chain length rather than position-based stickiness.
Tumble Mechanic
Industry term for Only Match's Cascading Wins. Winning gems vanish, new ones drop in to fill empty slots, and the grid re-evaluates for fresh clusters. Long tumble chains of 6+ are uncommon but possible, especially with a top-loaded grid.
Volatility (Variance)
How a slot's payouts are distributed. Only Match is rated Medium-High — frequent small clusters in the base, with the bigger spikes saved for deep cascade chains during Only Match Bonus. The medium-high rating positions it between casual cluster slots and high-vol Hacksaw-style designs.
Ways to Win
An alternative to fixed paylines. Only Match uses cluster pays, not ways-to-win. The cluster format is fundamentally different — wins depend on adjacent matching symbols rather than column-by-column positions. The two systems can't be directly compared on a per-line basis.
Wild
A symbol substituting for any regular symbol. Only Match's wild design is minimal — the cluster mechanic itself does the heavy lifting through cascade chains and persistent multipliers rather than wild substitutions. The Match Multiplier carries the value-escalation role that wilds typically play in line-based slots.
Win Distribution
How total payouts are spread across different win sizes. Only Match's Medium-High design spreads payouts: Only Match Bonus contributes ~50% of total RTP, base-game cascade chains ~35%, single-cluster wins ~15%. The persistent multiplier in the bonus skews returns toward the rare large hits.
100HP Gaming Catalog
100HP Gaming is a newer provider focused on cluster mechanics with mathematical honesty (no buy bonus on most titles). Only Match (January 2026) sits in their puzzle/match subgenre. Distribution skews European regulated markets with growing presence in LatAm operators.
6×5 Cluster Grid
Only Match's grid format. 6 reels × 5 rows = 30 cells. Pays through cluster pays — 5+ adjacent matching gems form a cluster. The 6x5 layout supports larger clusters than 5×5 grids, with up to 30-symbol mega-clusters covering the entire grid being theoretically possible.
Cascade Chain
Only Match's sequence of consecutive cascades from a single spin. Each cascade in the chain bumps the Match Multiplier by +1. At least one cascade after a winning spin: ~55%. Three or more cascades in one chain: ~12%. Six-cascade chain: ~1 in 80 winning spins.
Retrigger Mechanic
Only Match's bonus extension. Three additional scatter gems landing during the Only Match Bonus add 4 more spins to the counter, on top of remaining spins. Chained retriggers can stretch a 12-spin round past 20 spins with the persistent multiplier remaining active throughout.
Buy Bonus Restrictions
Only Match doesn't offer a buy bonus, so there are no jurisdictional restrictions on the buy. UK and Sweden block bonus buys on other titles, but 100HP Gaming's design choice to omit the buy means players in all regulated markets get the same playing experience.
