King Arthur

King Arthur Overview

King Arthur is a medieval legend slot from TaDa Gaming, released on 4 March 2024. It plays on a 5x4 grid with 20 fixed paylines, and it is built around two ideas: a duel in the base game that turns a reel wild with a multiplier, and a free spins round where the middle reel becomes a chained dragon’s lair. SlotCatalog lists an RTP of 95%, medium-high volatility, a maximum win of 10,000x the bet and stakes from 0.10 to 100.

Camelot on the Reels

The base game is set on stone reels against a green valley with a castle on the hill. King Arthur himself stands on the right in full plate armour, crown on his head and a sword raised over the grid. The premium symbols are the king, his Saxon rival in a fur cloak and iron crown, a golden crown, a knight’s helmet, a goblet and a jewelled ring, with the card royals A, K, Q and J filling the lower tier. The scatter is a castle tower with a golden SCATTER banner across it.

The Duel

The feature that makes the base game different is the duel. Our screenshots caught it in progress: the Saxon king steps in from the left with his sword drawn, facing Arthur on the right, and two multiplier labels flash across the reels – X1 on the blue side and X4 on the red. TaDa Gaming describes the mechanic this way: when a win lands, the VS symbol expands into a wild, and the multiplier attached to it is decided by the duel.

In another spin the Saxon king had taken the third reel as a full-height wild with an X1 label above it, and the game paid 48.000 at a 20 stake – 2.4x the bet. At X1 the duel adds no multiplier, but the full wild reel still links symbols across the grid on several lines at once.

A Win From the King Himself

The highest-paying symbol is Arthur. One spin in our session landed three Arthur portraits across the first two reels, and the line paid 100.000 – exactly 5x the 20 stake, with the win shown in large red-and-gold numbers across the grid.

Paylines and Stakes

The 20 paylines are fixed, so every spin plays all of them and the only choice is the size of the bet. With four rows instead of the usual three, each reel shows more symbols at once, which gives the lines more ways to cross the grid and makes a full-height wild reel – like the one the duel creates – cover four line positions in one go. Stakes run from 0.10 to 100 per spin according to SlotCatalog, and our session was played at 20 throughout.

The Symbols in Order

The two kings are the premium characters, with Arthur at the top of the table. Below them come the golden crown, the steel helmet, the goblet and the purple jewelled ring, and then the four card royals. The royals are carved stone letters; the premium symbols are drawn in full colour.

Triggering the Free Spins

Three scatters anywhere on the reels start the bonus. Our trigger had them on the first, second and third reels, each castle tower glowing as the round began.

The Dragon’s Lair

In the free spins the scene changes completely. The valley is replaced by a burning red sky, the reels turn to dark steel panels with shield icons, and the middle reel becomes a wooden gate locked by heavy chains – the dragon’s lair. On the left, a FREE SPIN column shows three shield slots that fill with crossed swords as the round progresses; our screenshots show one, two and then all three of them filled.

Arthur appears as full-reel symbols during the round. In one of our spins he covered the first, second and fourth reels, each with a 10X multiplier above it, while the chains still held the lair shut.

Opening the Lair

The last stage of the round opens the gate. Our final screenshot shows the chains gone and a red dragon inside the middle reel, with a huge 36X written across it. The closing screen then read “Congrats! You won – Total Win 720.000”: at a 20 stake that is exactly 36x the bet, so the multiplier on the dragon was the value of the whole round.

How the Numbers Add Up

The screen shows amounts with three decimals, so “720.000” is 720 and “48.000” is 48. With the bet fixed at 20 across our screenshots, every result can be read directly as a multiple of the stake: 2.4x from the duel, 5x from the king’s line and 36x from the dragon. The 10,000x ceiling is far above what we saw, and it is reached through the free spins, where the multipliers stack up.

Two Different King Arthur Games

If you search for this title at a casino, you may find two results. Next to this game, the casinos we checked also list King Arthur 10K Ways, a separate TaDa Gaming release with a different reel layout. This review covers the original 20-line King Arthur with the duel and the dragon’s lair, so make sure you open the right one.

What to Expect From a Session

Medium-high volatility means the base game will not pay on every spin, and the wins it does pay are mostly small line hits like the 2.4x and 5x results above. The free spins are where the game’s balance swings, and they can take a while to arrive. It is sensible to choose a stake that leaves room for a long run of base spins – the free demo on this page is a good way to see how often the duel and the scatters appear before you play for real money.

Who It Is For

King Arthur suits players who like a story-driven slot with medium-high volatility. The base game is steady, with the duel adding the occasional wild reel, while the real potential sits in the dragon’s lair, where full-reel kings and multipliers build towards one big reveal. A 36x round in our session shows the kind of result it can produce, with 10,000x as the published maximum. All six casinos we checked carry it.
