Power of Ten by Hacksaw Gaming: how one round adds up
Power of Ten is a Hacksaw Gaming slot whose whole character is an order of operations. Nothing about the result is decided by the reader, but a lot about it is easy to misread, because the prizes arrive after the lines, the prizes add to each other before anything is multiplied, and one of them stops the sum dead.
These six pages take that sequence apart stage by stage and keep two sets of figures separate throughout: what the studio's own product page states, and what large third-party listings publish instead. On this title the difference matters more than usual, because the one number everybody quotes is a number the studio does not print.
| Settled first | payline awards |
|---|---|
| Settled second | any landed Power Wheels |
| Combined how | values added, then the stake applied once |
| Wheel results | 10x, 100x, 1,000x or MAX WIN |
| Published ceiling | 10,000x the stake |
The studio's own still of the game screen, re-cropped here to the reel area alone. One line is lit across the grid and its award is shown on the board; the round total in the bar below it is a separate figure in a separate place.
The order a round is settled in
Four things happen, always in the same sequence. Ordinary line awards are worked out first. Any Power Wheel that landed on the grid, which has been sitting inactive while that happened, then spins and reveals a result. If more than one wheel is present, the numbers they reveal are added together. Only then is the stake brought in, multiplying that sum once to produce what the studio's own copy calls the definitive win.
Put the stake anywhere else in that sequence and the arithmetic comes out differently, which is the practical reason the order is worth knowing at all. A reader who assumes each wheel is converted to money as it stops, and the money then totalled, will arrive at the same answer by accident here — but will arrive at the wrong one the moment a figure is quoted as cash rather than as a multiple.
What the total win is calculated from
Every number on this site is a multiple of the whole stake for the round. A wheel showing a value does not pay that value; it contributes it to a sum that the stake then scales. The same holds for the ceiling, for the row table and for the figures the purchased entries carry. Nothing here is a multiple of a line, of a symbol or of a fraction of the bet, and no amount of money is ever the right way to state one of these values.
The practical consequence is small and useful: a write-up that lists this game's prizes in pounds and pence has silently chosen a stake for you. Those tables are not wrong so much as unfinished — they describe one bet level and read as though they describe the game.
One return figure is printed, four are certified
The product page the studio publishes for this title carries no return percentage. That page now asks an age question before it shows anything at all, so the readable record of it held here is a set of captures taken when this site was first built, and no return figure appears on them either.
Outside listings are where the familiar 96.23% comes from, and two of the largest also record what that figure actually is: the highest of four certified builds, 96.23%, 94.35%, 92.19% and 86.20%, with the copy an operator installs deciding which one applies. One of those same two listings headlines the second build rather than the first in its own attribute table while its prose quotes the first. A third site that targets this game by name puts the second build in its page title.
So the honest sentence is not a number. It is that this game is certified in four return builds, that the gap between the top and the bottom one is ten percentage points, and that the figure for any single copy lives in that copy's own information panel and nowhere else. The multiples page sets out what that does and does not say about a round.
What is here and what is not
There is no game on this site. No stake is taken, no balance exists, no account is offered and nothing on these pages opens a playable window. Several large listings do carry a free version of this title — at least five of them say so plainly, and none of the ones checked while this was written says the game is unavailable in that mode — but the way to reach one is to go to a listing or an operator, not to a reading site.
Nor is there a figure here for how often anything happens. One listing records a hit rate of 25%; no second source repeats it and the studio's page states nothing of the kind, so it is quoted as that listing's record and never as the game's specification. Two different sites give two different odds for the top result in the bought round, 1 in 10.39 against 1 in 13.33, which is reason enough not to repeat either as fact. The arrow rounds page says why that particular number is the easiest one on this game to get wrong.
Eight questions that come up about this round
What settles first in a round of this slot?
The paylines. A wheel that has landed stays inactive until every ordinary line award has been handled, and only then does it spin. The order is the studio's own wording, not an interpretation of it.
What values can one wheel show?
One of 10x, 100x, 1,000x or MAX WIN. A row filled with five of them drops the shortest of those and uses 100x, 1,000x or MAX WIN on each position instead.
If two wheels land, are the two prizes paid separately?
No. The numbers the wheels reveal are added first, and the stake multiplies the sum once. Two wheels produce one feature result, not two payments.
What is a multiple here a multiple of?
The whole stake for the round, not a line and not a part of the stake. That is why the figures hold at every bet level and why a prize quoted as an amount of money is only a prize at one particular bet.
What is the published ceiling?
10,000x the stake, and it is the one figure the studio's page and every outside listing agree on. A wheel showing the top result reaches it at once and the round stops there.
Is there a single return percentage for this title?
Not one that can honestly be printed alone. The page Hacksaw Gaming publishes for this game carries no return figure at all, and the two largest listings that do carry one record four certified builds — 96.23%, 94.35%, 92.19% and 86.20% — with the operator deciding which is installed.
How many lines and how large is the grid?
Outside listings record five reels and five rows and 19 fixed lines running left to right, and the studio's own screen capture shows that grid. Our source describes the five reels but states neither the row count nor the line count.
Can this slot be played on this site?
No. There is no game here, no demo window, no balance and no link dressed up as one. Several large listings do carry a free version of this title, and none of the ones checked says it is unavailable; this site simply is not one of them.
Carry on with
The stage-by-stage version is on the result order page, and what each number multiplies is on the multiples page. The two rounds that change the arithmetic have pages of their own: the arrow rounds, where a row either survives or pays nothing, and the three scatter counts, where the rule set changes rather than the prize. On a phone covers which figures have to stay legible when the screen is narrow.
