Stamp World

Stamp World is a philately-themed slot from KA Gaming, released on 26 November 2025. It plays on a 5x4 grid with 20 lines at medium-high volatility, and its central idea is a multiplier ladder printed across the top of the screen: x1, x2, x4, x8.

A Collector’s Album

The reels sit on a green baize page, surrounded by a scattered pile of real-looking postage stamps in sepia and faded colour – perforated edges, franking marks, portraits.

Every symbol is a stamp showing a country: France, the USA, Italy, China, the UK, Brazil and Australia, each drawn as a circular stamp with a landmark and a flag. An aeroplane stamp is the wild and a world map stamp is the scatter. The words 20 LINES run vertically down both edges of the frame.

France Is Worth Thirteen Australias

At the $300.00 total bet our session ran at, for five, four and three of a kind:

France – 6,000 / 2,250 / 750
USA – 3,600 / 1,350 / 450
Italy – 3,000 / 1,125 / 375
China – 1,350 / 450 / 225
UK – 900 / 300 / 150
Brazil – 675 / 225 / 105
Australia – 450 / 150 / 75

In multiples that is 20x the bet at the top and 1.5x at the bottom. There are no card symbols here and no filler tier – seven stamps, seven distinct values, stepping down evenly. That is rarer than it sounds; most modern paytables collapse their lower half into two or three shared figures.

The Scatter Barely Cares How Many You Land

The world-map scatter has the flattest ladder we have recorded:

5 scatters – 1,500.00
4 scatters – 1,200.00
3 scatters – 900.00

From three to five the prize rises by two-thirds. Compare that with France, where three to five multiplies the prize by eight.

The conclusion is clear enough: the scatter is not there to pay you, it is there to trigger something. Three of them are worth 3x the stake and five are worth 5x – a decent consolation either way, and deliberately not a reason to chase a fourth or fifth.

The Multiplier Ladder

A strip along the top of the frame shows four steps – x1, x2, x4, x8 – with a marker indicating the level currently in force. It doubles at every step rather than climbing by ones, so the top rung is eight times the bottom.

On a paytable where the best line is 20x, an x8 turns that into 160x. Nothing else in the game comes close to that kind of leverage, which makes the ladder the thing worth watching on every spin.

The Game Names Each Line

Wins are announced above the reels with the line number and the amount – ours read “LINE 7 WINS $75.00”, “LINE 12 WINS $75.00” and “LINE 10 WINS $150.00”. All three match the printed table exactly: $75 is three Australias, $150 is three UKs.

What The Session Produced

Three spin totals at the same $300.00 stake: $150.00, $375.00 and $982.23 – 0.5x, 1.25x and 3.27x.

The best came from a board with two aeroplane wilds on the fourth reel and a scatter beside them. Our balance fell from $65,557 to $54,854 over the session.

What KA Does Not Publish

KA Gaming maintains a public release spreadsheet listing RTP, volatility and maximum win for its games – but Stamp World is not in it, and the catalogues carry no return or ceiling figure either.

We have left both fields empty rather than print numbers we cannot stand behind. The line count we can confirm: the game prints 20 LINES down both sides of its own frame, and that is now on our data sheet.

What The Bet Changes

Everything scales with the stake. Our screenshots were taken at $300.00, where five French stamps pay $6,000 and three Australians pay $75. At a tenth of that stake every figure falls by a tenth; the multiples – 20x at the top of the table, x8 at the top of the ladder – never move.

More From KA Gaming

KA releases at a considerable pace across slots and arcade formats. Egyptian Goddess is a recent 25-line slot with multiplying wilds, Skeleton Party runs 243 ways with a scatter that pays 50x, and Tactical Flush shows the studio’s arcade side.

Who It Is For

Stamp World is for players who appreciate a theme nobody else has attempted. A stamp album is an odd subject for a slot and it has been done properly – perforated edges, franking marks, seven countries each with its own landmark. Underneath it is a clean twenty-line design with a properly graded paytable, no filler symbols, and a doubling multiplier ladder that can turn a 20x line into 160x. The reservations are what KA does not tell you: no published return figure and no maximum win, so the ceiling is a matter of trust. All six casinos we checked carry it.
