Oki Doki! GOLD-30 (沖ドキ！GOLD-30) is the 30-pai version of the Oki Doki! GOLD medal-type pachislot machine. Its core play is intentionally simple: a hibiscus lamp announces a bonus, while internal modes determine the likelihood of another bonus within 32G. GOLD adds the Kin-Doki mode, which can reconnect a completed chain to another Heaven-or-higher sequence.

Setting probabilities and payout rate
Setting probabilities and payout rate
Administrator research. This machine uses Settings 1, 2, 3, 5 and 6. Bonus initial-hit probability and payout rate both improve as the setting rises.
| Setting | Bonus initial hit | BIG | REG | Payout rate |
|---|---|---|---|---|
| 1 | 1/299.6 | 1/175.3 | 1/368.7 | 97.2% |
| 2 | 1/287.3 | 1/168.3 | 1/346.2 | 98.7% |

Setting-sensitive small roles
Setting-sensitive small roles
Administrator research. Cherry A is common across settings at approximately 1/52.5. Cherry B has a setting difference; the combined cherry rate therefore also changes with setting. For the statistical range below, only Cherry B is modelled so the same underlying setting-sensitive flag is not counted twice.
| Setting | Cherry B | Cherry combined |
|---|---|---|
| 1 | 1/168.0 | 1/40.0 |
| 2 | 1/152.4 | 1/39.1 |
| 3 | 1/145.6 | 1/38.6 |
| 5 | 1/136.5 | 1/37.9 |
| 6 | 1/128.0 | 1/37.2 |
Game flow
Game flow
A hibiscus-light notification announces a bonus. Internal modes govern both the effective bonus rate and the maximum game-count protection. Heaven, Dokidoki and Super Dokidoki are 32G-chain states; Kin-Doki is the GOLD-specific route that can connect back into Heaven-or-higher behavior after a chain ends.
The manufacturer describes Heaven as the series’ strongest Heaven performance at the time of release, with Kin-Doki added to make consecutive chains possible across a favorable-section transition.
Administrator research. Additional play and result interpretation:
A complete hibiscus-bonus cycle
- Normal play draws a pseudo-bonus. The hibiscus notification confirms a bonus; align the instructed combination and follow any stop navigation.
- Finish BIG or REG and then monitor the next-bonus game counter. A Kana-chan lamp stock creates a BIG 1G chain, while the 32G mode route is a separate mechanism.
- During the 32G route, another bonus redraws the next mode and restarts the next-bonus count. A chain length is therefore not the same as the length of one bonus.
- After the chain ends, read return-mode / normal-mode cues and the applicable protection. A section transition can select the model-specific special route.
Ceiling, reset and quit timing
Ceiling, reset and quit timing
Administrator research. Normal A and Normal B have a maximum 999G + α bonus ceiling. Return/Chance modes can use a 200G maximum. When a favorable-section transition selects Normal A or B, a separate draw can shorten the maximum to 399G; after a setting change that shortening draw is 25%.
The estimated maximum cash to the 999G bonus ceiling from 0G is approximately ¥34,000 under the site’s standard ¥1,000/46-credit assumption, the approximately 32G/50-coin base and normal play without penalties. Because the ceiling is 999G + α, actual cash can exceed the estimate slightly.
No separate fixed AT-interval ceiling is published; the game-count ceiling guarantees a bonus. After a bonus, do not immediately ignore the first 32G because internal modes can make a quick repeat bonus highly relevant to the machine’s core system.
BIG and REG
BIG and REG
Administrator research. BIG lasts 70G for approximately 210 coins and REG lasts 30G for approximately 90 coins. A lit Kana-chan lamp indicates a BIG 1G-chain reward. Bonus chains within 32G are driven by the internal mode structure rather than by a separate visible AT start screen.
Administrator research. Additional play and result interpretation:
| Bonus | Duration / approximate gain | Net speed |
|---|---|---|
| BIG (ビッグ) | 70G; approx. 210 coins | Approx. 3 coins/G |
| REG (レギュラー) | 30G; approx. 90 coins | Approx. 3 coins/G |
The gains describe the bonus portion, not a net profit from the start of the session. During a bonus, the published 1G-stock draws are cherry 1.0%, watermelon 3.3%, and guaranteed for a confirmed special role or middle cherry. Those are conditional draws after the indicated role; they are not standalone per-game probabilities.
The Kana-chan lamp is a BIG 1G-stock cue. A lit cue and a high-next-mode hint answer different questions: one announces a specific stored reward, while the other describes the next-bonus route.
Setting differences and identification
Setting differences and identification
Bonus initial-hit rates and selected small-role probabilities are the main numerical long-run indicators. Normal A/B effective bonus probability also improves at higher settings. Mode transitions have a large effect on short-term results, so do not treat a single fast chain as evidence of a high setting.
Administrator research. Additional play and result interpretation:
Separate normal-play initial bonuses from chained bonuses when recording performance. Mode allocation strongly changes the short-term bonus frequency; a long chain is useful for the current reward state but is not a direct high-setting confirmation. The setting rows for this model omit Setting 4; do not fill that gap with an interpolated value.
Statistical setting ranges
Japanese Slot Guide calculation. The expected counts and central 95% count ranges below are calculated from the listed setting probabilities with a binomial model. They describe ordinary statistical variation under that probability; they are not confidence percentages for the actual setting.
Cherry B
Administrator-research per-game Cherry B probability. Cherry A is common across settings; only the setting-sensitive Cherry B flag is modelled rather than also modelling the derived combined-cherry rate.

How to read this: overlapping ranges are expected. A result inside one setting’s range can also be plausible under another setting. Do not use these ranges as a setting confirmation or as a promise of future results.
Modes and 32G behavior
Modes and 32G behavior
Normal A/B use the deepest 999G protection. Return and Chance use shorter protection, while Heaven, Dokidoki, Super Dokidoki and Kin-Doki are centered on a 32G repeat-bonus window. Dokidoki and Super Dokidoki use stronger continuation behavior than standard Heaven, and Kin-Doki guarantees a route into Heaven-or-higher after its bonus.
Administrator research. Additional play and result interpretation:
| Mode family | Next-bonus maximum | Progression |
|---|---|---|
| Normal A / B (通常A・B) | 999G | Normal B supports progression toward Heaven |
| Return / Chance (引き戻し・チャンス) | 200G | Separate earlier normal-play routes |
| Heaven (天国) | 32G | Ordinary short chain |
| Doki Doki (ドキドキ) | 32G | Approx. 80% loop; falls to guarantee mode |
| Super Doki Doki (超ドキドキ) | 32G | Approx. 90% loop; falls to guarantee mode |
| Guarantee (保障) | 32G | Post-Doki protection |
| Kin-Doki (金ドキ) | 32G | Its bonus leads to Heaven or higher |
A 32G bonus is an observed result; it does not on its own identify which of the 32G modes was active. Strong loop modes and guaranteed stock can produce similar timing. Use a specific hibiscus pattern or sound law where its interpretation is published, and leave the exact mode unclassified otherwise.
Advantageous-section behavior
Advantageous-section behavior
Administrator research. Additional play and result interpretation:
When the GOLD section route changes
The published favorable-section reset triggers are a setting change, the end of Heaven or higher and a 2400-coins + α payout. There is no visible favorable-section lamp that identifies every transition. The transition is a chance for Kin-Doki, not proof that Kin-Doki was selected.
On a setting change, the published initial allocation is Normal A 50.8%, Normal B 9.4% and Chance 39.8%. The separate 25% ceiling-shortening draw applies when Normal A or B is selected; it is not an unconditional 25% chance for every reset machine.
How to play
How to play
No navigation: stop the left reel first. If numbered stop instructions appear, press the stop buttons in the displayed order (1, then 2, then 3). A symbol-target instruction tells you which symbol to aim for; follow it together with any displayed stop order.
During normal play, use left-first and aim around the BAR on the left reel so cherry/watermelon patterns remain identifiable. Normal unassisted middle-first play is not the standard procedure. During bonus play, follow all push-order navigation; when no navigation appears and a rare-role cue occurs, use the normal small-role target procedure.
