The purchase share counts features with an actual ten-spin addition after a fisherman milestone: 16 of 50 in run one and nine of 50 in run two; 30 and 26 natural features were extended. Starting awards of 10, 15 or 20 spins are excluded, and added batches use 2x, 3x and then 10x collection multipliers, with no fourth extension.

One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 120 ordinary rounds in this sample. Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

| 50 bets | bust at spin 105 |
| 100 bets | bust at spin 168 |

The runs are played back to back as one series, one bet size. A different session can bust earlier or never; treat this as a measured example, not a rule.
How it plays
7 rules screens from the game
A pair of floats can pay; the other regular symbols need at least three. The five-by-three board carries ten paylines, with combinations anchored to the first reel. Fishermen are wilds confined to free spins and substitute for symbols other than the scatter.
Groups of three, four or five fish scatters open with 10, 15 or 20 spins respectively. During the feature, each fisherman gathers the money values on all visible fish; several fishermen collect the same set separately. Fish also retain their ordinary line payouts, and a lone fisherman can randomly cause extra money symbols to appear.
Collected fishermen accumulate even on a screen without fish. The fourth, eighth and twelfth unlock another ten spins, using 2x for the first added batch, 3x for the second and 10x for the third. Each added block waits until the preceding batch finishes, so filling the bar does not immediately change the multiplier on the current spins. The third extension is the last available.
A feature purchase costs 100x the ordinary stake and can open with any of the three scatter awards. Normal play uses ten credits; Ante uses fifteen and raises the natural-feature chance, while purchases are available in the ordinary mode. The declared RTP remains 96.50% for ordinary play, Ante and purchased features.
This build labels its volatility low and caps ordinary-mode winnings at 2,100x the stake. Standard bets span USD 0.10 to USD 250; the USD 375 maximum printed in the rules includes the fifteen-credit Ante setting. At the tested USD 2 stake, the feature purchase costs USD 200.

Verdict
Frequent features, flat return
Reel Action repeated itself: 93.05% in run one, 92.68% in run two, 92.86% across the pooled 20,000 USD 2 rounds (approximate 95% CI 82.55%–103.17%, which only says how precise that mean is), under the 96.50% build. Paying rounds were 21.0% and 21.74% of each run; 15,726 rounds returned zero, and the droughts peaked at 34 and 41 rounds.
Features are frequent here: 76 and 91 natural starts, one per 120 rounds, and their full rounds supplied 55.6% of pooled payouts with a 46.5x median; 56 of the 167 were extended by a fisherman milestone. Run one's round 4467 (347.5x) remains the largest feature, run two's best stopped at 182x, and the base game never passed 100x in either run; the listed 2,100x maximum stays far away.
In purchase terms the game pays its way only in aggregate: the 100 USD 200 tickets brought back USD 21,222, 106.11%, while the median ticket paid USD 55, 85 tickets fell under price and seven tickets above fivefold hold the surplus. Ticket 26 of run two (USD 2,542, 45 spins) replaced run one's USD 1,701 as the top ticket, and run two's batch closed at 92.63%.
- Ninety-one natural features in run two, one every 110 rounds
- Forty-five spins on ticket 26 of run two paid USD 2,542, 12.7 times its price
- Seven tickets of the 100 paid fivefold or better
- Consistent returns: 93.05% in run one, 92.68% in run two
- Fifteen winners in 100 tickets; the median ticket paid USD 55
- The base game never paid more than 100x in 20,000 rounds
- Forty-one blank rounds in a row in run two, from 5525 to 5565
- Neither run reached the 96.50% build, 92.86% pooled
Run 01·2026-09-15·93.05%
The profitable purchase total needs its distribution beside it. Fifty tickets cost USD 10,000 and returned USD 11,959, an average recovery of 1.1959x per ticket, alongside a median of just 0.3675x, or USD 73.50. Although 41 purchases finished below USD 200, the five largest supplied USD 7,560 of the return. Those large outcomes explain the positive total without making the median purchase profitable.
Collection dominated the natural bonus component: USD 9,782 from fish and USD 528 from line awards. Together these produced USD 10,310 in free-spins-only winnings out of USD 18,609 returned across the ordinary series. The largest complete ordinary round paid USD 695, whereas the largest individual screen in the ordinary series paid USD 260; a feature total is not a single catch.
Round 1439 separates advancement from payment. Its seventh free spin had a fisherman, no fish and no line award, yet completed the first four-fisherman bar. The initial ten spins paid USD 85; the added ten carried 2x but produced no fishermen and added USD 0. Reaching the next multiplier created an opportunity to collect, not a payout of its own.
Run 02·2026-10-14·92.68%
Ticket 26 opened with 15 spins, reached 45 through three fisherman milestones and collected USD 2,542, 12.7 times its price and the largest purchase of the series; ticket 14 ran 40 spins for USD 2,008. The best natural feature, round 1534, collected five times over 20 spins for USD 364, 182 stakes, and no ordinary screen paid more than USD 82.
In total the 10,000 USD 2 rounds returned USD 18,535, a 92.68% RTP, within half a point of run one's 93.05%; 7,826 rounds paid nothing and the longest blank stretch was 41 rounds. Ninety-one natural features arrived, one per 110 rounds, 26 of them extended, and supplied USD 10,344 over their full rounds, 55.8% of payouts, with a 44.5x median. On the purchase side, 50 tickets at USD 200 paid USD 9,263, 92.63% of cost: 44 tickets under price, a USD 51.50 median, and tickets 26 and 14 holding USD 4,550 of the money between them.

FAQ
7 questions · answered from the log
Has Reel Action's measured RTP changed with a second run?
No: 92.68% after 93.05%, 92.86% across 20,000 USD 2 rounds against a 96.50% build. Run two paid USD 18,535 on USD 20,000.
What took ticket 26 to 45 free spins?
It started with 15 spins from four scatters and gained ten at each of three fisherman milestones; its collections paid USD 2,542, 12.7 times the USD 200 price. Ticket 14 followed the same route to 40 spins and USD 2,008.
At which rate did run two trigger free spins?
Ninety-one features in 10,000 rounds, or one per 110, after one per 132 in run one, and the longest wait was 503 rounds, from 4969 to 5473. Pooled, a feature comes every 120 rounds.
What do the frequent features pay?
Modest sums: run two's 91 features paid a median 44.5x and the best 182x, USD 364 at round 1534; together they supplied USD 10,344, 55.8% of the run's payouts. No feature in 20,000 rounds has passed 347.5x.
What dragged run two's purchase batch under 100%?
Everything beyond the top two tickets: 26 and 14 paid USD 4,550 of the batch's USD 9,263, the median was USD 51.50, 44 tickets paid under USD 200, and the batch closed at 92.63% of cost against 119.59% in run one.
Has any Reel Action base-game spin passed 100x?
No. The ceiling is still 100x, at round 8270 of run one; run two's best ordinary screen paid USD 82 (41x). The listed maximum is 2,100x the stake.
Is a 15-spin start an extension?
No. Fifteen spins come from four scatters at the trigger, as on ticket 26; an extension is a ten-spin addition after a fisherman milestone. Run two logged 26 extended natural features and nine extended purchases.
