REC · NATURAL TRIGGER

Heartstopper selects Aces and Purple Hearts for seven Be My Angel spins, ending at FUN 38.50 including FUN 0.50 from the trigger. Recorded in a separate browser session, outside the statistical samples.

Across the whole run the 43 natural bonuses split into 10 under 20x, 18 between 20x and 50x, 10 between 50x and 100x and 5 at 100x or more, and together they made up 30% of everything the game returned. The wait between two triggers ran from 2 to 925 spins. Payout figures here are FS-only, in ordinary stakes; the trigger payout is excluded.

Every feature started with seven Be My Angel spins. 2 of 43 features completed an inner column, and each newly full column added three spins, matching the remaining-spin counter. The longest features ran for 10 spins, at rounds 2327 and 8650, each after one completed column.

Lil' Devil keeps four positions on each of its six reels, giving 4,096 ways before any Angel Wild changes the layout. Matching symbols connect from the left, with the Purple Heart paying for two reels and other ordinary symbols requiring three. Six-reel Purple Heart ways pay 10 stakes apiece, while six Scorpions pay 5; Devil Wilds substitute on reels 2 through 5. The original 2019 game is classified High / Extreme by Evolution, and this demo accepts FUN 0.10 to FUN 20 per spin.

An Angel Wild occupies reel 3 or 4 with one of five multipliers, stepping from x4 to x12 in increments of two. Combinations using both Angels multiply their values together, reaching x144 when both show x12. Three or more cabin Scatters open a choice between Be My Angel and Dynamite Lover, alongside a separate Scatter payment. Three, four, five and six cabins pay 6, 20, 50 and 100 stakes respectively.

Be My Angel begins with seven spins and designates a symbol that becomes a persistent Wild on the four inner reels. Completing a column with four sticky Wilds adds three spins, once per column, for a maximum allocation of nineteen. A completed central column also becomes an Angel, starting at x4 and increasing its multiplier by two on each subsequent spin until x12. Heartstopper enhances this choice by making Purple Hearts sticky as well as the selected symbol.

Dynamite Lover supplies twelve spins in which winning symbols leave the grid and replacements fall into their positions. Its Dynamite Wilds occur on the central pair of reels, with a multiplier starting at x1 and rising by one whenever a reaction uses a Dynamite Wild; values on one reel add, while values across the two reels multiply. Three Scatters extend this mode by six spins, and every Scatter beyond three adds six more. The Heartstopper version begins the Dynamite multiplier at x5.

Exactly two cabins contribute one Heart to a forty-Heart meter, which opens the enhanced feature when filled. Each stake keeps its own Heart tally, so switching the bet switches the relevant meter. The tested choice throughout was Be My Angel, whose stated RTP is 96.43%; the Help gives 96.31% when choosing Dynamite Lover instead. This client offers ordinary spins and feature selection, with no bonus-purchase option.

Verdict

Two symbols, still seven spins

At round 1141 the fortieth Heart opened Heartstopper, which made a randomly chosen King sticky alongside the Purple Heart, yet all four inner reels stayed incomplete. The seven spins paid FUN 273.90. At the next meter completion, round 2327, Tens joined Purple Hearts and reel 3 filled on the fourth free spin: that column added three plays, its Angel rose from x4 to x12 by spin eight, and ten plays paid FUN 528.00.

Nine forty-Heart cycles completed, each taking between 815 and 1,186 rounds with the first counted from the start of the series, and 30 Hearts were left on the meter when the series stopped. The 9 enhanced features returned a median of FUN 36.90 from free spins against FUN 29.75 for the 34 scatter-triggered ones. Every entry used Be My Angel at a fixed FUN 1 stake, so the two groups share the sticky-symbol rules and differ only in whether Purple Hearts also turn Wild. Round 1141 shows the difference: the second sticky symbol added paying Wilds without completing a column or extending the seven spins.

Measured upsides
  • The Heart tally carried through all 34 scatter-triggered features without a reset.
  • Purple Hearts provide a second sticky-symbol target in the enhanced Be My Angel feature.
  • A completed central column adds three spins and an Angel that can grow from x4 to x12.
Measured downsides
  • 8 of 9 enhanced entries finished without completing any of the four sticky columns.
  • Filling the forty-Heart meter took between 815 and 1,186 ordinary spins per completed cycle.
  • Angel Wilds appeared without a payout in 486 of the 1,194 ordinary rounds that showed them.

FAQ

5 questions · answered from the log
Do three Scatters wipe the Heart meter?
Lab answer

No. All 34 scatter-triggered bonuses, 33 from three cabins and one from four, left the Heart count where it was. Only a completed forty-Heart cycle reset the tally, so scatter bonuses and the meter progressed independently at the fixed FUN 1 stake.

Will my Hearts follow a change of stake?
Lab answer

The Help specifies a separate tally for each stake. All 390 Hearts here were collected at FUN 1; 360 completed the 9 enhanced entries and 30 remained afterward. A different stake uses its own progress, rather than taking that FUN 1 tally with it.

Does an Angel Wild guarantee a payout?
Lab answer

An Angel multiplies a paying combination that uses its position. Among 1,194 ordinary rounds with at least one Angel, 486 returned zero; the multiplier did not create a matching way by itself. Angels occupy reels 3 and 4, so matching symbols must still connect from the first reel.

Does this test include Dynamite Lover's 96.31% RTP?
Lab answer

Be My Angel was selected on every entry, making 96.43% the relevant theoretical figure; Dynamite Lover's 96.31% belongs to the alternative choice. Recorded winnings were FUN 8,816.30 from FUN 10,000 staked, a measured 88.16%. A normal approximation gives a 95% interval of 72.60% to 103.73% around that sample mean, not a range that future sessions must stay within.

What is the free spins frequency in Lil' Devil?
Lab answer

43 features arrived in 10,000 spins, about one per 233 rounds: 34 from three or more cabins, roughly one per 294, and 9 from a full Heart meter. Most stayed at seven spins; only rounds 2327 and 8650 completed a column and reached 10, while full columns on all four inner reels would allow 19.
