The Kingdom of Cardia: discover Betsoft's fantasy world

The Kingdom of Cardia is an online slot developed by Betsoft and released in June 2026. Part of the studio's THE Series, this title takes you into a medieval fantasy kingdom inspired by the four suits of a deck of cards. For players who enjoy mixing online dice slots with more traditional reel games, this guide covers how it works, its symbols and its many bonus features.

How The Kingdom of Cardia works

The Kingdom of Cardia is built on a grid of 5 reels and 4 rows, offering 1,024 ways to win. Winning combinations form from left to right on adjacent reels, without needing to line symbols up along a fixed payline.

The backdrop depicts a royal garden with castle towers rising in the distance, an atmosphere that visually recalls the world of Alice in Wonderland, reimagined around the four royal houses of the playing cards.

Stakes on The Kingdom of Cardia range from €0.15 to €37.50 per spin, keeping it accessible to a wide range of budgets.

The symbols in The Kingdom of Cardia

The lowest-paying symbols are stylised icons of the four classic card suits: a green spade, a blue club, a purple diamond and a red heart. Landing five identical icons of this kind pays 0.66 times your stake.

The premium symbols represent characters and objects from the four royal houses: a crown, a trumpet, a princess, a green knight, a court jester, a queen and a king. These are the symbols that generate the biggest wins in the base game.

The Wild symbol appears only on reels 2, 3 and 4. In the base game it substitutes for all standard symbols to complete winning combinations. During the free spins it becomes a multiplier Wild worth 2x or 5x. These multipliers can combine with one another, reaching up to 125 times the value of a combination.

The Key of Cardia is a special symbol that appears only on the first reel. It triggers the Cash & Collect mechanic by forming a winning combination with the Cash or Jackpot symbols on the other reels. Cash symbols can appear on reels 2 to 5, with values ranging from 0.33x to 66.7 times the stake. Jackpot symbols, on the other hand, appear only on the fifth reel.

The bonus features of The Kingdom of Cardia

The Pick Feature: Royal Wealth or Ultra Kingdom

Landing 3, 4 or 5 Scatter symbols triggers a pick game (the Pick Feature). The player must choose between two options.

Royal Wealth Free Spins awards 8, 15 or 20 free spins depending on the number of Scatters, with multiplier Wilds and none of the special symbols that could interrupt the flow of wins.

The Ultra Kingdom Bonus Spin offers a single spin guaranteed to produce either a Cash win, a Jackpot win, or the trigger of one of the two secondary bonus games.

The Plinko game

The Plinko game is triggered either through the Ultra Kingdom Bonus Spin or when the Key of Cardia forms a winning line up to a Plinko symbol on the fifth reel. The playing field turns into a Plinko board: you have 4 balls to drop, and each landing slot displays a random multiplier between 1x and 25x, which changes after every drop.

The Hi-Strike Smash game

Hi-Strike Smash works on a similar principle to Plinko: it is triggered via the Ultra Kingdom Bonus Spin or when the Key of Cardia lines up with a Hi-Strike Smash symbol on the fifth reel. Special symbols smash open positions on the grid to reveal additional prizes.

The feature buy (Bonus Buy)

The Kingdom of Cardia offers a direct bonus buy option at rates below the industry norm: Hi-Strike Smash is available from 26.6 times the stake, and Plinko from 40 times the stake. This lets you access these features straight away, without waiting for a natural trigger.

The technical details of The Kingdom of Cardia

The maximum RTP of The Kingdom of Cardia is 96.25%. As with many Betsoft games, this figure can vary depending on the configuration chosen by the operator, so it is worth checking the paytable at the casino you are using.

Volatility is rated high: the base game produces few frequent wins, and most of the potential rests on triggering the bonus features. The maximum win is capped at 10,000 times the total stake and is mainly reachable during Royal Wealth Free Spins, thanks to the combined Wild multipliers.
