Boxing King Demo by TaDa Gaming

Five red boxers pay 5x on a line in Boxing King, while five old blue-corner fighters pay 4x. The red corner wins every pairing on this TaDa Gaming slot’s paytable, glove over fist and red trunks over blue, yet the game keeps its two sharpest ideas for the Free Game, where neither corner’s line pays are the main story.
The red-haired fighter who fronts the game sets the tone. He stands shirtless with his gloves up in a guard, a tall swept-up quiff over a heavy frown, a gold WILD belt round his waist, and dark red FIGHT shorts below it.
Free Play Features

Free Game Combo Ladder
In this sport slot, the Combo Multiplier is a Free Game feature. When a free spin wins, the winning symbols vanish and replacements fall from above to fill the holes, and from the second matching in the same spin onward, the multiplier climbs through five levels.
| Matching within one free spin | Combo Multiplier |
|---|---|
| Second | x2 |
| Third | x3 |
| Fourth | x5 |
| Fifth | x6 |
| Sixth or more | x8 |
| No match | Resets to x2 for the next spin |
Six matchings in a single free spin reach x8, the top level, and any matching after the sixth stays at x8. Once a refill produces no match, the spin is over and the multiplier drops back to x2 for the next one. The ladder has no memory between spins.
Ring Bell Spins
Scatters don’t appear during the Free Game, so they can’t add spins once the round is running. A brass ring bell marked FREE SPIN does that job instead. Each bell adds one extra spin, two bells add two, and the number of extra spins the round can collect is unlimited. The bell takes no part in a matching itself. It stays on the board while the other symbols keep matching and clears once they stop, ready for the next spin.
Belt Wilds
A gold championship-belt plate serves as the WILD, and it can stand in for everything on the reels bar the Scatter and the FREE SPIN bell. In the main game, it lands only on reels 3 and 4. During the Free Game, its reach widens to reels 2 through 5, and the number of WILDs that appear is random. The plate shows WILD in large raised gold letters, and the belt isn’t listed on the paytable.
Scatter Pays
Two fighters squaring up on a yellow starburst make the Scatter, one with spiky white-blue hair and the other the red-haired boxer. They pay 2x with no line needed, the same 2x whichever count from 3 to 5 lands, and 3 or more of them trigger the Free Game too. Three Scatters give 8 free spins, 4 give 12, and 5 or more give 20.
That splits the Boxing King demo, a slot set in a lit boxing ring, into two clear halves. The main game is an 88-line grid with cascades, and the Free Game adds the climbing multiplier and the bell.
How to Play
RTP
In Boxing King’s main game, a line win has to open with a natural matching pair across reels 1 and 2, because lines pay from reel 1 and the WILD can’t reach either of those reels outside the Free Game. Once the free spins start, the WILD can cover reel 2 as well, so only reel 1 still needs a natural symbol.
There are 88 paylines across the 5×5 grid. A line pays when the same symbol runs from reel 1 across consecutive reels, so three red gloves on reels 1, 2, and 3 count, while three on reels 2, 3, and 4 don’t. Winning symbols disappear, and new ones fall down to fill the gaps.
Inside the Free Game, the order of wins starts to matter. After a winning free spin clears and refills, every symbol on screen can form the next matching, and the game pays each matching at the Combo Multiplier level for its place in the chain, from x2 on the second matching to x8 from the sixth.
The RTP TaDa gives Boxing King is 96.5%. On the other side of the ledger, Boxing King caps a single round at 10,000x. Set against a top line pay of 5x, that cap is far above anything a single line pays at face value, and the only multipliers the game describes belong to the Free Game. That’s where a five-red-boxer line takes the x8 level, if it lands as the sixth matching of a free spin or later.
Payouts
Red-corner symbols outpay their blue match at five. The red boxer leads at 5x against 4x for the old fighter, the studded red glove pays 3x against 2.5x for the blue-wrapped fist, and red trunks pay 2x against 1.5x for the blue pair. The same order holds for four and three of a kind. Below the fighters, A and K share one row of pays and Q and J share another.
| Symbol | 5 | 4 | 3 |
|---|---|---|---|
| Red boxer | 5x | 2x | 0.5x |
| Old boxer (blue) | 4x | 1.6x | 0.4x |
| Red glove | 3x | 1.2x | 0.3x |
| Blue fist | 2.5x | 1x | 0.25x |
| Red shorts | 2x | 0.8x | 0.2x |
| Blue shorts | 1.5x | 0.6x | 0.15x |
| A, K | 1x | 0.4x | 0.1x |
| Q, J | 0.5x | 0.2x | 0.05x |
| Scatter (no line needed) | 2x | 2x | 2x |
Five blue shorts at 1.5x still outpay five A or K at 1x, so even the weakest fighter beats the strongest letter. At three of a kind, the spread is narrow, from 0.05x for Q or J up to 0.5x for the red boxer. The WILD and the FREE SPIN bell have no rows, and the table states every pay against the total stake.
Read across the columns and the pays line up in other ways too. Four red boxers pay 2x, level with five red trunks and with any Scatter win. Five A or K pay 1x, the same as four blue fists, and five Q or J pay 0.5x, the same as three red boxers. On this table, a long line of low letters and a short line of the top fighter can be worth exactly the same.
Ultimate Slots Verdict
The main game is an ordinary 88-line slot, with a 5x top line and WILDs held to reels 3 and 4.
Boxing King's Free Game lifts it, pairing a Combo Multiplier that climbs from x2 to x8 across matchings within one spin with FREE SPIN bells that add one spin each, without limit.

Detailed Review
How Our Gameplay Went
Boxing King earns 3.3/5 because its two strongest ideas, the Combo Multiplier and the ring bell, both belong to the Free Game, while the 88-line main game around them is ordinary. Outside the bonus, five red boxers at 5x is the best line on the table.
The Free Game is where the slot gets interesting. A free spin that keeps matching climbs from x2 on its second matching to x8 from the sixth, and the bell adds one spin per symbol with no limit while Scatters stay off the reels. Pairing a multiplier that builds within a spin with a spin count that has no upper limit is the smartest decision TaDa made here, and a WILD that can reach four reels gives those cascades more to work with.
The main game isn’t bare, and this review gives it credit for that. 3, 4, or 5 Scatters pay 2x on their own without a line, and the red-versus-blue table gives each fighter symbol a rival. The art follows the same split, with flames behind the red tiles and blue lightning behind the old boxer and the fist.
The weak spot is the reset. A free spin can build to x6 or x8 over a run of matchings, then a single refill that misses sends the next spin back to x2, and watching a high level vanish on one miss is the deflating side of the round. The bell softens that a little, because an extra spin is a fresh run at the ladder, but no level carries over into it. Boxing King has been out since March 2021, and the reset remains the part of its Free Game most likely to frustrate.
In free play, come for the Free Game and treat the rest as warm-up.
