Heart of Earth Deluxe (Swintt) – Review & Demo Play

Free to Play Demo for Heart of Earth Deluxe

I ran the free demo of Heart of Earth Deluxe before staking real cash, which helped me test the 5x3 layout and five-line setup at different stakes. The demo mirrors the live maths, so you feel the medium volatility, the hit rate rhythm, and how the Wild and Scatter combine. It's a tidy way to see how the Lucky expanding symbol behaves in free spins and to gauge whether the 5,000x top potential sits within your risk comfort.

QUICK INFO for Heart of Earth Deluxe

Heart of Earth Deluxe runs on 5 reels and 3 rows with 5 fixed paylines. Bets span 0.05 to 100 per spin. The default RTP is 95.52 percent, though other versions exist at 92.10, 90.04, and 85.53 percent, so check the lobby figure. Volatility sits in the medium bracket with a reported hit frequency of 17.63 percent. The headline payout reaches 5,000x your bet, which is fair for this kind of classic five-line build.

The release date is 29 November 2023, and it follows the 2019 original. Core features include a combined Scatter and Wild symbol, a Free Spins round with expanding symbols via a Lucky pick, and an optional Bonus Buy in some markets. There is no jackpot. The set-up keeps things simple, leaning on those expanding wins in the bonus to drive the bigger outcomes while the base game nudges along with steady, low-line hits.

Heart of Earth Deluxe by Swintt

This deluxe take keeps the underground adventure feel of the first slot, sending you into a fiery world packed with treasure and odd creatures. The colour palette leans dark with hot reds, which suits the premise. It stays familiar, so if you liked the original's mood, you'll feel at home. I found the story beats light, yet the atmosphere is consistent enough to frame the features and give the free spins some pressure.

Mechanically it's a traditional 5x3 with five lines, medium volatility and that mid range RTP profile. Wilds cover regular subs, Scatters trigger the bonus, and the Lucky expanding mechanic is the headline during free spins. A Bonus Buy shortcut exists where permitted. I rate the interface as clean and old-school, with straightforward controls and a pace that suits quick sessions. It's not flashy, but it does the job without fuss.

Paytable & Paylines in Heart of Earth Deluxe

The paytable mixes standard royals and theme icons across five fixed lines. Wins can land quickly due to the low line count, yet big steps tend to come from feature play. The look stays dark and heated, backing the tunnelling theme with reds and metal touches. With only five paylines, line discipline matters; I often nudged stake sizes to ride the medium variance, letting the better symbols carry the base returns.

Low pays are the card royals A, K, Q, J, and 10, paying about 20x to 30x for five of a kind. High pays are the compass, the drill tank, and a golden plant, paying roughly 150x up to 400x for five. The standout is the brave explorer, worth up to 1,000x for a full line. Those figures set the stage for the bonus, where expansions can connect across lines for chunky totals.

Game Features in Heart of Earth Deluxe

The slot uses a Scatter and Wild combined symbol. As a Wild it substitutes for all regular symbols, smoothing base spins and lining up the stronger icons. As a Scatter it is the trigger, and landing three or more starts the bonus. I liked how the dual role keeps the grid active; when it hits in base, it still teases the feature, and when it stacks up, you're straight into the free spins.

The Free Spins round starts with 10 spins on three or more Scatters. Before the round begins, the game picks a Lucky symbol. This chosen symbol can expand to fill a reel when it lands, paying on the five lines even without adjacent positions, which is the key driver for sizeable wins. The behaviour echoes classic expanding mechanics, and with five lines the maths stays punchy rather than scattershot overall.

There's a Bonus Buy option in markets where it's allowed, jumping straight to the feature for a set price. I used it to test how often the Lucky symbol delivers, and the take-away is clear, the best hits come from multi-reel expansions backed by a high-pay icon. Outside the bonus, the combined Scatter and Wild keeps spins engaging, though the real ceiling shows in that 5,000x maximum during extended testing sessions.

Verdict on Heart of Earth Deluxe

Heart of Earth Deluxe is a simple five-line slot with a clear hook, a fair 5,000x cap, and a medium tempo that suits session play. The visuals and audio feel basic, and the RTP sits below the market average in several versions, so I always check the percentage offered. Even so, the Lucky expanding feature and the combined Scatter and Wild give it enough edge. Fans of the 2019 release will likely feel comfortable giving it a go.
