Bell is one of the most common symbol combinations (called “Yaku”) in Japanese pachislot. When a bell combination appears on the reels, the player typically receives a small payout—usually a few coins.

Bell outcomes appear frequently and are designed to keep the gameplay flowing by offering regular rewards.
They do not usually lead to big wins, but in AT (Assist Time) mode, bells may play a key role in accumulating coins efficiently.

💡 Tip: Some machines may use sound or animation to highlight when a bell has been hit, though in most cases it is a quiet, routine outcome.

Replay is a common outcome in pachislot where no coins are paid out, but the player is allowed to spin again without losing a credit.

This symbol combination helps to extend playtime and is often used to maintain the pacing of the game.
In some cases, replay outcomes are tied to internal mechanics, such as transitioning into bonus states or indicating hidden progress.

💡 Tip: Unlike in Western slots, replays in pachislot are an intentional and important part of game design, not just “misses.”

Rare symbols (known in Japanese as “Rea-yaku” / レア役) are special combinations that appear less frequently on the reels but have a greater impact on gameplay.

Unlike regular symbols like bells or replays, rare symbols may trigger:

• Bonus entry chances
• State transitions (like CZ or AT)
• Dramatic animations or sound effects

Common examples of rare symbols include:

• Cherry
• Watermelon (Suika)
• Chance Pattern (チャンス目)

Rare symbols do not always result in an immediate payout, but they often indicate a shift in the machine’s internal state, leading to more exciting gameplay.

💡 Tip: Each machine may treat rare symbols differently. The same cherry might be a weak role in one machine and a high-chance trigger in another.

Cherry is one of the most common rare symbols (レア役) in Japanese pachislot.
When a cherry symbol appears on the reels, it often increases the chances of triggering a bonus, entering a special mode, or progressing toward a state transition.

There are generally two types of cherries in many machines:

• Basic Cherry (弱チェリー): Low chance of leading to a bonus
• Powerful Cherry (強チェリー): Higher probability of triggering bonuses or events

The classification depends on how the symbols align and may vary by machine.

💡 Tip: In many machines, a strong cherry is indicated when a bonus symbol lands on the middle of the right reel.
Also, some machines may internally register a cherry even if it doesn’t visibly stop on the left reel.
However, if the player fails to aim for and stop the cherry correctly, the machine may not award any coins—even though the internal draw still takes place.
Always try to follow the timing and visual cues to ensure proper payout.

Watermelon is another common rare symbol (レア役) in Japanese pachislot.
It usually appears less frequently than cherries and is often associated with chances to enter bonus zones or trigger internal state changes.

Stopping the watermelon correctly often requires more precise timing than other symbols. In some machines, the player must aim carefully to stop it across all three reels, or it will “miss” and result in no payout.

There are also machines where the strength of the watermelon is judged by its alignment:

Basic Suika may appear diagonally or partially aligned.

Powerful Suika often lines up horizontally (parallel) across the reels, indicating a better chance of a bonus or strong event.

💡 Tip: Watermelon symbols are often placed near the BAR or 7 icons on the left reel.
Try to aim for these as a visual reference.
If you fail to stop the reels correctly, some machines will not pay out any coins—even though a rare role has been internally registered.

A Chance Role (Japanese: チャンス目) refers to a reel stop pattern that does not result in an immediate payout or win, but is internally treated by the machine as a trigger for special event chances, such as entry into a bonus zone (CZ) or an AT mode.

Unlike regular symbols or winning combinations, chance roles are often disguised as normal “misses” or unusual stop patterns. However, the machine uses these patterns to quietly perform an internal lottery, increasing the chances of something exciting happening soon.

These are not the same as “reach-me” patterns (which signal a confirmed bonus), but rather function as hidden signals to the player.

💡 Tip: Even though you won’t receive coins right away, recognizing a chance role helps you understand when the game might shift.
Some machines highlight them subtly; others use animations or sounds to hint at a possible bonus.

A Guaranteed Role (確定役) is a rare symbol combination that guarantees a bonus or major event when it appears.
Unlike chance roles or regular rare symbols, a guaranteed role always results in a confirmed outcome—such as triggering a Big Bonus, entering AT (Assist Time), or activating a special storyline mode.

These roles are extremely rare and considered the most valuable outcomes in pachislot.
Depending on the machine, they may:

• Directly lead to the highest-tier bonus or jackpot
• Override current state or conditions (even in low modes)
• Be accompanied by flashy animations or sound effects

📊 Typical Appearance Rates

Guaranteed roles typically occur at rates such as:

• 1 in 3,000 spins
• 1 in 8,192 spins
• Or even rarer in some machines (e.g., 1 in 16,384)

These probabilities vary by machine, but they reflect how special and impactful these outcomes are.

💡 Tip: Some guaranteed roles may not be labeled clearly on the screen.
If you hit one—especially with a rare line-up like triple 7s or specific BAR placements—it’s not only a confirmed win,
but it may also trigger additional rewards, such as a long bonus round or even a freeze (フリーズ) effect depending on the machine.
