How Hold and Win Actually Works

The loop: land coins, hold, respin

The base game plays like any other slot until the trigger combination lands. From there the machine swaps to a separate board where only coins matter. Each coin carries a value in multiples of your bet, and the respin counter resets to three every time a new one arrives. What becomes of the coin splits our nine carriers in three. On the six single-feature carriers a collector sticks on the middle reel and gathers the value of every coin that lands. Their rules end the round when the respins run out, and none of the six prints a full-board ending. Gold Express keeps its coins where they land and ends the round on spent respins or on a board of all 20 symbols. Both Gold Express and Little Farm pay the GRAND jackpot for that full board. 4 Supercharged Clovers is the third kind, with clovers in place of coins that stay where they land. A blue Collect clover gathers the whole board each time one lands, and a full board pays the GRAND or, on the five-row Super board, the SUPER.

Above the coin values sits a jackpot ladder, usually four tiers with fixed prices. On our nine carriers the tiers run from 15x the bet at the bottom to 1,000x, 2,000x, 5,000x or 10,000x at the top. The top tiers are priced into the maths as properly rare events. The engine's appeal is arithmetic you can watch: the board state tells you exactly what the round is worth at any moment, which no cascade game can offer. My studio-side habit is to call this the most legible bonus format in the building, and I mean that as measured praise.

Nine carriers, one engine

Method in one line: flat stakes, natural triggers only, no bonus buys, and a feature round counts from natural trigger to settled payout, in each game's provider demo build. The full protocol lives on the methodology page.

Each row pools the logged demo sessions of its game, three per game except Diamonds Power's two, one recorded here and the rest on the game's dedicated network sites. Per-session tables, screenshots and Session IDs sit in the linked reviews, and the exact rules live on each game's rules page: Thunder Coins, Royal Joker, 777 Coins, Gold Express, Little Farm, Thunder Coins XXL: Multicoin, Royal Coins 2, 4 Supercharged Clovers, Diamonds Power.

What 473 feature triggers actually paid

Five of the six single-feature carriers sit unusually close together, one round per 129 to 155 spins, and the two carriers that split their clock with Free Spins triggered faster still: one per 63 for Gold Express and one per 82 for Little Farm. The sixth single-feature carrier, Diamonds Power, pooled at one per 247 over two logs, the slowest clock on this page. 4 Supercharged Clovers, with one feature and no Free Spins to share it with, pooled at one per 92 and sits between the two groups. Royal Coins 2 is the one carrier here with a studio figure beside its clock: Playson's sheet for operators states one Bonus Game per 133 spins, and its pool logged one per 137. Hold and Win stays the most punctual bonus family across the games our four mechanic pages cover. Cascade games on this shelf sit between one per 167 and one per 493 by comparison. The payouts are another matter, and the gap between promise and log is wide. The best complete rounds in the nine pools were 351x, 664x, 264x, 204x, 130x, 181x, 245x, 253x and 231x. The figures they are sold under are four kinds of number. Playson's guides for operators give 5,150x for Thunder Coins, 21,150x for Royal Joker and 4,030x for Royal Coins 2 as the largest payouts seen in 50 billion simulated spins, a result of simulation and not a rule of the game. The 6,000x of 777 Coins is a line on its intro screen, as is the 1,057x of Diamonds Power, a drawn sum that its rules never set as a cap, and the 2,000x of Gold Express and the 5,000x of Little Farm are the prices of their GRAND jackpots. Thunder Coins XXL prints no maximum at all, and 4 Supercharged Clovers prints two figures, a 12,400x cap in its rules and 15,000x on its intro screen. Only the 204x of Gold Express cleared a tenth of the figure beside it; nothing else came near that line, and Diamonds Power stands outside this measure, with no printed maximum to set its 231x against.

The jackpot ladder deserves its own honest line, so here it is. Across the rounds behind all 473 feature triggers, the ladders paid three MAJOR, at least fifteen MINOR and at least thirty-nine MINI coins or clovers between them, and nothing higher. 4 Supercharged Clovers supplies 32 of those through its Mystery feature, 25 MINI and 7 MINOR clovers in 67 pooled rounds, with no MAJOR and no full board. Thunder Coins XXL adds a MINI coin on the frames of its 150x round, and a MINOR that sat on its board at a round's close without entering the payout. Royal Coins 2 supplies twelve of them: its 47 rounds took in two MAJOR, four MINOR and six MINI coins, each added to every crown standing when it landed. Diamonds Power adds one MINOR and five MINI inside its 18 pooled rounds, the MINOR inside its 231x best, and its bolt collected one more MINI in the base game, which no round counts. A Free Spins round on the two dual-feature carriers cannot collect a jackpot tier, so the ladder's sample there is smaller than the trigger count: 28 boards among Gold Express's 46 portal rounds and 15 among Little Farm's 30, with the sister logs' splits as their pages publish them. Royal Joker's board and 777 Coins' ladder produced nothing at all in 86 combined rounds, and the one MAJOR outside Royal Coins 2 belongs to Gold Express's 204x round. The tiers are printed in each game's rules, and they are also priced like lottery seats: visible at every spin, collected almost never. Rounds are carried instead by ordinary value coins, and the occasional side engine doing its work, like the Royal Bonus collector behind that 664x.

One more finding from the logs: a headline feature can sit in plain sight and still be missed by the bookkeeping. Thunder Coins prices its whole identity on the Thunder Bonus, and our session log does not tag its collects, which is how this page once reported it absent. On paper no bonus round starts without it. In the sample our own session never played a round without it, sixteen out of sixteen, and it cashed coins on 54 spins outside the bonus. Its XXL successor adds a multiplier to the collector, and that one appeared in eighteen of 39 rounds and never above x7. Royal Coins 2 shows the collector at its plainest, each crown on the reel adding each new coin to its own total: 25 of its 47 rounds paid more than the face value of their coins, and every one of the 25 closed on more than one crown. Diamonds Power gives that same crown the Thunder Coins strike as well, under the name Power Bonus: in two logs the bolt paid 748 bets on 99 base-game spins, one spin in 45, and fourteen of its 18 rounds closed on more than one bolt. The split between base game and rounds has a page of its own, what the base game pays and what the bonus pays, built on our nine logs.

What is not Hold and Win

Coins on the screen don't make a game Hold and Win by themselves. Coin Princess x1000 fills its board with multiplier coins, and there is no holding and no respin counter behind them. Those coins live inside a cascade engine, and the sum resolves per sequence. The distinction isn't cosmetic, and it matters for bankroll planning, because cascade features arrive rarer and swing harder. The cascade family has its own page: how cascade slots actually pay.

All nine carriers here run as free provider demos on our Demos and Rules hub, with in-game rules one click away. A demo run teaches the board logic faster than any diagram, and the 18+ rule applies to free play as much as to real stakes. Line machines with no board sit on the classic line slots page, and free spins that collect toward one settlement sit on the free spins ladders page.
