How does the Bonanza Megaways free-spins multiplier work?

Which Bonanza does this explain?

This is Bonanza by Big Time Gaming, the six-reel mining game also listed as Bonanza Megaways by GB operators. Its horizontal carts add symbols above the four middle reels. Winning symbols are removed and replacements can form another win before a new spin begins.

Sweet Bonanza, Big Bass Bonanza and Bonanza More Gold are separate titles. Their multiplier symbols, collection features or added modifiers do not establish the rules of the original BTG game. The provider name in the game information is a useful check when several search results share “Bonanza”.

Megaways describes how combinations are counted on the changing reel layout. The free-spins multiplier is a separate calculation. Our explanation of Megaways slots covers the ways mechanic without assuming that every Megaways game shares this bonus.

How does GOLD start the free spins?

The published GB rules start the feature when four gold-bar Scatters spell GOLD. The initial award is 12 free spins. Additional Scatters on the qualifying result add five spins each; for example, one extra makes the initial award 17. This is a count of spins, not a 12× or 17× cash prize.

Virgin’s detailed table specifies three or four cart Scatters for the five- or ten-spin retrigger. Its nearby general wording about “every” Scatter should not be read as a promise that one cart always adds spins. Betano’s GB description gives the same three/four retrigger amounts.

The game feature is also separate from a casino promotion awarding spins to an account. A promotion’s game, spin value, expiry or balance terms need their own check; they do not change the GOLD trigger inside the slot.

When does the win multiplier increase?

A reaction is the replacement of winning symbols: they disappear, new symbols arrive, and the game checks the resulting layout. In free spins the multiplier begins at 1× and increases by one after each winning reaction. The order matters: settle the win at its applicable factor, then carry the higher counter into the next evaluation.

A layout can contain several winning combinations. Their eligible awards are added for that evaluation; several simultaneous combinations do not mean that the same layout should be settled repeatedly at successively higher factors. The rise follows the reaction, rather than the number of symbols removed.

The cited GB pages describe a feature multiplier rising after reactions, but do not document every screen transition or build-specific display. Follow the multiplier and win history in the game actually open. The calculation below stays within one free-spin reaction sequence, so it does not rely on an undocumented reset assumption between separate free spins.

A worked example: £2.30, not the final counter times everything

Assume one free spin starts at 1× and produces three successive winning layouts. At the example’s selected stake, their aggregate cash awards before the feature multiplier are £0.40, £0.20 and £0.50. These amounts are invented teaching inputs, already converted from the hypothetical paytable into pounds; they are not observed Bonanza results.

The arithmetic is (£0.40 × 1) + (£0.20 × 2) + (£0.50 × 3) = £2.30. After the third winning reaction the counter can show 4× for the next evaluation. That does not turn the three earlier wins into £1.10 × 4 = £4.40. If the next layout has no win, its award remains £0.

Do not multiply by the stake a second time. If the example used a 20p triggering stake, the three pre-multiplier cash amounts already reflect that stake. Multiplying £2.30 by £0.20 again mixes two different calculation stages. Conversely, an amount already shown as a final multiplied cash win should not receive the feature factor again.

£2.30 is the illustrative credit for these three wins, not the net profit for a session or a forecast for a whole bonus. Any other feature wins, the triggering paid spin and earlier paid spins would need separate accounting.

Do extra spins increase the multiplier automatically?

An extra-spin award changes how many free spins remain. A winning reaction changes the multiplier. They are different events, so adding five spins does not by itself add five to the multiplier or multiply the balance by five.

For example, assume the current spin has already been deducted and the remaining-spin counter shows two. A qualifying three-cart award adds five, leaving seven. That arithmetic does not say what any of those seven spins will pay. Read any cash win on the same result separately from the extra-spin notification.

Sky’s published rule keeps the triggering stake for the duration of the free spins. An award of additional spins is not a new request to increase that stake. Do not interpret a larger spin counter as evidence that a higher cash stake has been applied.

Why more Megaways is not another cash multiplier

The supplier describes a maximum of 117,649 ways. A ways count measures possible symbol paths on the current layout. It is not a cash prize and should not be multiplied into an award that the game has already calculated.

For a simple invented layout, two matching positions on the first reel, three on the second and one on the third can make 2 × 3 × 1 = 6 matching three-reel paths, provided they meet that symbol’s win rule. Six paths is a combination count, not evidence of a 6× feature multiplier. Additional reels, symbol requirements and wilds would need their own paytable evaluation.

This also explains why copying a maximum-ways figure into the cash example is wrong. The ledger starts with aggregate cash awards for each winning layout. The applicable combinations and stake have already been accounted for before the separate free-spins factor is applied.

Does “unlimited multiplier” mean an unlimited payout?

The public GB descriptions call the multiplier unlimited. That describes the rising multiplier mechanism; it does not override a game or operator’s monetary payout limit. Nor does it guarantee that enough winning reactions will occur to reach a large factor.

A high counter can still be followed by a losing layout. Neither a GOLD near-miss nor a run without a bonus establishes when the next trigger will arrive. The rules cited here do not supply a trigger probability or a personal expected wait, so there is no sound spin target to calculate from them.

The supplier’s public RTP figure describes a theoretical game specification, not a promised return for a bonus or a short session. Check the exact build’s rules for its return figure and monetary limits. The slot RTP explanation shows why an advertised percentage cannot be used to predict the next few results.

What should you check if your result looks different?

• Confirm that the title is the original Bonanza by Big Time Gaming, rather than another Bonanza game or a sequel.
• Compare the GOLD trigger with the feature’s cart-Scatter retrigger table; they are different events.
• Read the multiplier before the relevant win, then the increase after the reaction. Do not apply the final counter retrospectively.
• Establish whether a displayed amount is a paytable multiple, pre-multiplier cash or a final cash award before doing any extra multiplication.
• For an unexplained result, keep the game name, time, stake and round identifier, plus the rules or win-history screen showing the amount. Ask the operator to reconcile that recorded round.
