Inside The King Base Game

Visually, The King centres on with king character. For review purposes, that theme is separated from the rules: In-Game Free Spins, the reel format and the combination model decide how a paid round is evaluated.

How In-Game Free Spins Works in The King

Endorphina documents 6 named mechanics for The King: Wild, Risk Game, Bonus Pop, In-Game Free Spins, Scatter, Multiplier. The primary review angle is In-Game Free Spins; the remaining labels are checked for where they enter, what they modify and when they reset.

Wild in The King

On a 5x3 screen, Wild can affect several possible combinations without creating a win by itself. Observe its permitted reels and its interaction with Risk Game before assigning value to a partial match. That test is specific to The King's 5x3 setup and should be repeated after any stake change.

Risk Game in The King

Treat Risk Game as a separate decision after the 10 result has already been calculated. The demo should confirm the success choices, stopping limit and whether Wild winnings are eligible for the same step. For The King, the win history should reconcile that behaviour with the published 10 calculation.

Bonus Pop in The King

The product page confirms Bonus Pop without compressing its full rule set into the catalogue. Check when it appears on the 5x3 screen, what it changes and whether that change is evaluated through 10 or another mode. For The King, the win history should reconcile that behaviour with the published 10 calculation.

In-Game Free Spins in The King

In-Game Free Spins is the no-cost round set named for The King. Test whether the 5x3 format changes, whether SCATTER can retrigger and whether Wild is enhanced, collected or cleared during the sequence.

Scatter in The King

For Scatter, the practical review point is the transition from the base game: what activates it, what changes and what restores ordinary play. Wild provides the closest comparison in the published feature list. That test is specific to The King's 5x3 setup and should be repeated after any stake change.

Multiplier in The King

A visible factor is not useful without its base amount. In the The King demo, trace Multiplier from trigger through calculation and note when it returns to its starting value on the 5x3 reels.

The King Base Game Before Free Spins

Before considering bonus modes, read The King as a 5x3 game with 15 visible symbol positions. The official sheet lists 10. A visible match is payable only when it occupies one of the documented patterns and meets the required symbol count.

Endorphina publishes 0.1 EUR to 90 EUR for The King. At the listed floor, 100 rounds represent 10 EUR of total turnover before returns; at the ceiling they represent 9,000 EUR. That gap makes stake selection more important than the visual size of one win.

The King Symbols: SCATTER and the Paytable

SymbolDocumented rolePublic payout note
SCATTERBonus or feature-trigger symbolUp to 500x the base bet in the described combination
WILDWild or substituting symbolUp to 900x the base bet in the described combination
TOP PAYING SYMBOLHigher-value paying symbolUp to 75x the base bet in the described combination
OTHER SYMBOLRegular paying symbolUp to 75x the base bet in the described combination

Among the The King values exposed on the public page, WILD is described at up to 900x the base bet. The next documented example is SCATTER at up to 500x. These examples do not replace the full paytable, which controls the required symbol count and eligible reel positions.

96.07% RTP and High Volatility

96.07% is the long-run return published for The King, leaving an implied house edge of about 3.93%. Applied only as an illustration, 1,000 units of turnover correspond to 960.70 units of theoretical return and 39.30 units of theoretical loss; one session can finish far from either figure.

The high-side volatility label makes stake size and available round count the main controls: feature value may be concentrated in less frequent outcomes, and increasing the stake does not make a trigger due. For The King, this risk label should be considered together with 0.1 EUR to 90 EUR and the 10 combination model.

A Focused The King Demo Test

  • Open the help screen first and confirm 96.07% RTP, high volatility and the 0.1 EUR to 90 EUR interval.
  • Keep one virtual stake while checking how the 10 combinations pay across the 5x3 grid.
  • Follow SCATTER from landing to settlement, especially if it starts In-Game Free Spins.
  • Watch Wild and Multiplier in the same session, since one animation is too little evidence.
  • Check the total stake again after any optional mode, device switch or autoplay setting.
  • Use the result history to split a paid spin from awarded spins or bonus steps.

Who Is The King Best Suited To?

The King is most relevant to players studying how an awarded-spin mode differs from the base reels. Its 5x3 format and 0.1 EUR to 90 EUR published range make the minimum-stake demo the sensible place to decide whether the controls and feature timing are comfortable.

NewCasinoStop Verdict on The King

The King earns its place in the Endorphina catalogue through In-Game Free Spins rather than theme alone. The 5x3 format, 10 model and 96.07% RTP are clearly documented; the unresolved point is the unpublished maximum-win ceiling. The official demo is useful for comparing In-Game Free Spins with Risk Game, but the casino information panel remains decisive.

The King Sources and Verification

Game-level specifications, feature labels, symbol examples and artwork were checked on the official Endorphina page for The King. Where that page does not publish a maximum win or complete static paytable, this review leaves the value unclaimed and directs readers to the loaded rules.

The King Questions and Answers

What RTP does The King use?

Endorphina publishes 96.07% for The King. Verify the same percentage after opening the game, since approved operator versions can differ.

How are wins formed in The King?

The King uses a 5x3 setup with 10. Its paytable defines direction, required matches and any special rule for SCATTER.

What should I check in the In-Game Free Spins feature?

Use the The King win history to separate the In-Game Free Spins trigger from its awarded steps, then confirm when accumulated values or counters reset.

Is The King suitable for a short session?

The King has high volatility, which does not predict a short result. Compare that risk label with the 0.1 EUR to 90 EUR range and set a fixed limit.

Can The King be tested for free?

The official The King play-money build is embedded at the top of this review where regional and browser rules allow access. Its virtual results cannot be withdrawn or used to predict real-money play.

The King is intended only for adults of legal gambling age. Set an affordable loss and time limit, never chase a previous result, and treat the demo as interface practice rather than a strategy test.
