Sayonara Bloodboys by Energi Slot Overview

Sayonara Bloodboys by Energi brings cartoon demons, moonlit temples and neon colours to its Japanese setting. Its expanding wilds share a mechanic with Wanted Dead or a Wild, but here a growing demon pile fights opponents to collect their hat powers.

The Oni Pile gains size, multipliers, lives or movement by defeating opponents. Bonuses replace a fixed spin count with survival: play continues until its lives run out, with a maximum win of 50,000x the bet. Explore these distinctive battles in the free demo on BonusTiime.

Sayonara Bloodboys Slot Features

The Oni Pile, The Bloodboys, The Duel, Bonus, Lives and Shields, The Dojo, Bonus Hunt and the buy options shape Sayonara Bloodboys into a layered system where each spin can trigger duels, life changes, shields, and bonus survival.

The Oni Pile

The Oni Pile is the wild and pays nothing on its own. It stands in for every paying symbol, but a line only counts if the first symbol after it is not an Oni Mask or a bloodboy. In the base game, it usually lands as 1×1.

It can also arrive as a heap and grow through the round. The listed heaps are 1×1, 2×1, 2×2, 3×2, 3×3, 4×3, 4×4, 5×4 and 5×5. When it covers the full board, each line made entirely of the pile pays as five Lanterns, times the total.

The Bloodboys

The Bloodboys pay on no line, and at most one can appear on each reel. Each one fights The Oni Pile, and the hat colour decides what the pile gains after the clash. That makes the symbol set both a blocker and a progression system.

  • AKA: grows the pile to the next heap.
  • KIN: adds the hat value to the pile total.
  • Midori: adds one life, up to 5.
  • AO: moves the whole pile to a random spot.

The Duel

The Duel happens whenever The Oni Pile is on the board and every bloodboy fights it from reel 1 to reel 5, top to bottom. The pile either wins and takes the hat power, or the sword hits and removes a life.

After all duels finish, every winning line through the pile is multiplied by its total. In the base game and Bonus Hunt, the pile has one life and its total lasts one spin. In a bonus, the total carries through the whole run.

Bonus

Bonus starts when 3 or more Oni Masks land anywhere in a single spin of the base game or Bonus Hunt. Masks count wherever they land, even if the pile later grows over them. The trigger opens a no spin count bonus where the pile stays on the board until it loses all lives.

  • 3 Oni Masks: Bonus with 3 lives and 0 shields.
  • 4 Oni Masks: Super Bonus with 3 lives and 1 shield.
  • 5 Oni Masks: Epic Bonus with 3 lives and 3 shields.

Lives and Shields

Lives and Shields control how long the bonus can keep going. Every bonus starts with 3 lives, while Max Risk starts with 1. A green hat adds one life, up to 5, so the run can stretch further if the pile keeps winning.

Magic Shields absorb sword hits before lives are lost. Super Bonus starts with 1 shield and Epic Bonus starts with 3. When a shield blocks a hit, it breaks, the bloodboy is beaten, and the pile takes its power.

The Dojo

The Dojo is the standard spin mode. The Oni Pile can land on any spin, fight every bloodboy on the board, and 3 or more Oni Masks open a Bonus. A blank board is a valid outcome, which keeps the base game honest and unpredictable.

Bonus Buy

Bonus Buy lets you purchase features once or keep them active so every spin buys them at the shown price.

  • Bonus: x100 the bet; no spin count, pile growth and power gains.
  • Super Bonus: x200 the bet; starts with a magic shield.
  • Mystery Bonus: x300 the bet; 50% no bonus, 43% Super Bonus, or 7% Epic Bonus.
  • Max Risk: x1,000 the bet; 1 life, with collected gold hats multiplying its total up to x1,000.
  • Bonus Hunt: x2 the bet per spin; Oni Masks and The Oni Pile land more often, and it stays on until you turn it off.

Sayonara Bloodboys Slot Review

Sayonara Bloodboys builds its identity around a dark Japanese demon setting, but the real hook sits in the Oni Pile, the Bloodboys and the shrine lit nighttime presentation. The comic style keeps the screen readable while still giving each clash a clear sense of movement and escalation.

The slot plays off its high volatility and 50,000x ceiling, so the base game can feel sparse when the board goes quiet. That said, the pile fighting bloodboys, growing through hats and carrying its total through bonus rounds gives each hit a real purpose instead of a simple spin and stop loop.

Sayonara Bloodboys offers life-based survival runs through natural bonus triggers and Bonus Buy options, without guaranteeing rewards for longer sessions or feature purchases. The 96.10% RTP supports the design, but the real selling point is the duel system, which makes it more distinctive than many line based releases.
