Easy First-Play Guide
Basic Specifications
A bonus draw is performed every game.
The main trigger is a bonus-indicating reel pattern; aim for a bonus through a wide variety of reel stop patterns and effects.
There are two bonus types: “Big Bonus” and “Regular Bonus”.
BIG is about 300 medals or more (including BT), and consists of Bonus game and JAC games.
After the Bonus game, Diagonal replay leads to a JAC game; lining up the Red 7 enters “RAIJIN LOOP”, turning it into a bonus that can award about 480 medals or more.
REG awards up to about 107 medals.
Normal-state Gameplay
During Normal state, a bonus draw is performed every game.
The main bonus routes are standalone bonus hits and bonus-indicating symbol combinations, and Simultaneous Wins with Replay, Cherry, or Watermelon also exist.
Whether a bonus has hit is indicated by effects and bonus-indicating reel patterns.
A bonus-indicating reel pattern stop or the “WIN” lamp lighting makes a Bonus Highly likely.
In addition to familiar “Cue sound”, “Lights off”, and “Flash” effects, new “Lightning Strike Effect” and “SPARK CHALLENGE” features are included.
Various rules exist depending on the effect.
| Normal-state Effect Rules | |
| Effects | Rule |
| Cue sound | Replay denied An odd-sounding “? sound” means blank or Bonus. |
| Lights off | The more reels go dark, the higher the Hit likelihood. If accompanied by a Cue sound, the Hit likelihood rises further. |
| Flash | Suggests Hit likelihood according to the Winning combination and Flash pattern. A contradiction with the corresponding winning combination: Bonus Highly likely |
| Lightning Strike Effect | RAKURAI occurs between the first and third stops. |
| With omen: For minor hits No omen: Bonus hit likelihood increases (Omen = cabinet-frame LED lights when the Lever is turned on) |
|
| SPARK CHALLENGE | When a minor symbol plus a specific flash occurs, pressing the CHANCE button after the third stop triggers it. On the next game, “%” indicates the Bonus hit likelihood. |
| [Specific Flash Patterns] •Replay + SAMIDARE •Cherry + Spark or Discharge •Watermelon + V Shape or Lightning Strike SP |

| Ones digit is 5 | blank or BB Highly likely |
| Repeated digits | rare minor symbol or higher |
[Effects Mode]
Effects Mode can be set from the menu screen.
There are two modes, each with different effect content.
| Features by Effects Mode | |
| Mode | Feature |
| STANDARD | Mode equipped with original effects |
| When Watermelon is established, it is accompanied by 2 lights off or more, or a Lightning Strike Effect. | |
| CLASSIC | Mode that recreates the Effect Rules of the original Thunder V. |
[reel slip display function]
Pressing the button for the reel stopped first again displays the reel slip count in the window below the left reel.
[Bonus-entry reel pattern display function]
After bonus alignment, holding the middle button displays “Ready!” on the LCD below the reels.
On the next lever after the display, the main reels show the Reel stop pattern from when a bonus is established.
[RIZIN Zone]
After BB ends, it enters RIZIN Zone.
It continues for 33G, and while active it is displayed on the LCD below the reels.
There are three effects during RIZIN Zone: “PANEL FLASH”, “Thunderclap Notice”, and “SPARK CHALLENGE”.
When the above effects do not occur, there is no chance of a rare minor symbol, so no minor symbol can be missed.
Also, after RB ends during RIZIN Zone, it enters RIZIN Zone again.
| Effect Rules during RIZIN Zone | |
| Effects | Rule |
| PANEL FLASH | Corresponds to Replay, Bell, or Cherry |
| Thunderclap Notice | Corresponds to Cherry or Watermelon |
| SPARK CHALLENGE | Occurs in some cases when Replay, Cherry, or Watermelon is established (Unlike Normal state, it occurs without pressing the CHANCE button) On the next game, “%” indicates the Bonus hit likelihood. |

Information
It strongly follows the feel of the series machines.
It is a balanced spec that combines the easy-to-hit appeal inherent to Normal type machines with a satisfying Number of medals won.
Includes many replay-value elements such as Effects Mode selection, winning pattern collection, and the reel slip display function.
Equipped with a complete (*) function.
(*) A function that enters play-stop state when 19,000 medals are won in one day, using the point where the medal difference is most negative as the baseline. In that case, the machine gives advance notice. The play-stop state is unlocked by a setting change.
