Power of Ten a reader’s notes on one Hacksaw Gaming slot, written for Britain

One symbol, three games › The feature set

Power of Ten features, from the Wheel to the Arrow run

Four symbols carry this game between them, and only one of them behaves like a slot symbol at all. This page takes them in turn, then sets the two routes into a feature side by side: the scatter you wait for and the entry the studio sells, which is what its FeatureSpins name has always meant.

The black panelled salon wall and polished floor the game is set in, lit by five warm ceiling spots
The setting the studio built the title around: panelled walls, floor spots and a deliberately quiet palette that leaves the gold of the symbols to do the work.

The special symbols, one at a time

Four symbols do the work. One pays on its own, one substitutes, one opens doors, and one exists only behind a door.

The Power Wheel is the cash-prize symbol and the reason the game exists. It does not join combinations. It waits for the ordinary line wins to be settled, then spins and reveals a prize paid as a multiple of the stake. Its full behaviour, the addition rule and the stronger set it uses on a full row are set out on its own page.

The Wild has one sentence to its name and it is worth noticing how short that sentence is. It substitutes for every symbol in the paytable. It does not multiply, it does not stick, it does not become a Wheel, and it does not interact with the feature symbols at all. In a game whose main symbol has four different behaviours depending on how many of it land, a Wild with exactly one rule is a design decision rather than an oversight: it keeps the base reels legible so that the Wheels can be the complicated part.

The FS Scatter is the key to the three bonus games. It is counted, not lined up, and the count is what selects the round. Three, four and five scatters do three different things, which is the subject of a separate page here.

The Power Arrow never appears in the base game. It only exists inside High-Roller FeatureSpins, where it is the only symbol that can land at all, and its job is to build complete horizontal rows across all five reels.

High-Roller FeatureSpins and the descending Arrow run

This is the most unusual round in the game and the easiest to describe wrongly. During High-Roller FeatureSpins the ordinary symbol set is gone. Only Power Arrows land, and they do not land evenly: our source gives the distribution as five Arrows on the first reel, four on the second, three on the third, two on the fourth and one on the last. Drawn out, that is a descending staircase across the board.

The target is a horizontal row of five Arrows with no gap in it, and a completed row awards 10,000x as a cash prize. The arithmetic of the staircase is what makes the round tense rather than arbitrary. The first reel can supply an Arrow to every row at once, so after one reel nothing is lost. The last reel supplies exactly one, so by the end at most one row can still be alive. Every reel in between is a filter, and a row that misses a position is dead for the rest of the round and visibly so.

That is why the round reads as a sequence rather than a spin. A reader is not waiting for a symbol to appear somewhere; they are watching five candidate rows get cut down to one or to none, with the result legible on the board rather than in a counter. It is also the only part of the game where the ceiling can be reached by a shape rather than by a Wheel reveal.

What a bought entry costs, and who says so

FeatureSpins has meant a purchased entry in this studio's titles for years, so the existence of a bought route is not an inference from a third party: it is in the name of the feature on the studio's own page. What the studio page we hold does not do is print a price.

One outside write-up does, and it prices four separate things. A BonusHunt entry at three times the stake, which it describes as making a trigger several times more likely rather than granting one. Deck of Fortune at a hundred times. Whopping Wheels at two hundred. High-Roller FeatureSpins at a thousand, with a stated chance of the ceiling on each spin of the round. Those four prices are that page's figures, they are corroborated by nothing else we hold, and they are printed here on that basis rather than as a specification.

Two things are worth separating out of that. The first is that a BonusHunt entry and a feature entry are not the same purchase: one buys odds, the other buys the round, and a reader who confuses them will be surprised by what their money did. The second is that availability is decided where the account is, not by the game. Bought entries are switched off entirely in several markets, and a feature that exists in the title is not the same as a feature a given cashier will show.

Not stated here: which operators offer the purchase, what it costs at any named one of them, and whether it is available in Britain. We hold nothing that settles any of those, and a guess dressed as a fact would be worse than the gap.

Theme and design: why the board is square

The setting is a panelled salon in black and gold, lit from above, and the symbol set is dice, card suits, chips, crowns and a cut blue gem. It is a quieter presentation than this studio usually ships, and the restraint is doing a job rather than decorating. On a board where one symbol can pay thousands of times the stake on its own, the thing that has to be instantly readable is which cells hold that symbol.

The square five-by-five board serves the same purpose. A full row of five is a meaningful event twice over in this game, once for Wheels and once for Arrows, and on a square grid a full row is the whole width of the screen and impossible to miss. Five rows also means five chances at that shape per spin rather than three, which is what makes the Arrow staircase work as a watchable sequence instead of a coin flip.

The parts readers ask to have separated

What does the Wild do here?

It substitutes for every symbol in the paytable and nothing else. That is the whole of its rule, and it has no relationship with the Wheels.

What is a Power Arrow?

A symbol that only exists inside High-Roller FeatureSpins. During that round nothing else can land, and the Arrows arrive across the five reels in a descending run.

Our source gives the run as five on the first reel, four on the second, three on the third, two on the fourth and one on the last.

How does an Arrow round pay the maximum?

A complete horizontal row of five Arrows, with no gap in it, awards 10,000x as a cash prize. One empty position and that row is finished for the round.

The remaining questions are about the bought entry, which is the part of this game that outside pages describe most and the studio page describes least.

Is High-Roller FeatureSpins the same thing as a bonus buy?

FeatureSpins is the studio's own name for a purchased entry, so yes, that is what it is. One listing puts the High-Roller price at a thousand times the stake.

That price is the listing's figure. The studio page we hold names the feature and describes it without printing a price.

What is BonusHunt FeatureSpins?

A cheaper purchase that buys likelihood rather than a round. The same listing prices it at three times the stake and says it makes a trigger several times more likely.

Does buying a feature change the return?

Nothing we hold says it does, and nothing on this site claims it does. A purchase is a way of reaching a round, not a way of improving one.

The symbol under all of it is on the Wheel page, the three scatter rounds are separated on the bonus games page, and the numbers behind the descriptions are on the figures page. The opening page sets out how the pieces fit together, and the phone page covers what changes on a small screen.

How old are you? The tab waits for an answer

The next tab belongs to a gambling operator, where this slot is played with real money. Britain sets the floor for that at 18, the same in every nation and region of the United Kingdom.
