Hold-and-spin features look simple on screen, yet a handful of rules decide how long a round can run. Bull Rush, a Konami pokie with 5 reels and 50 fixed paylines, gives a clean example through its Bull Blitz Feature. This guide splits the mechanic into four parts: trigger, locking, grid fill and prize tiers.
Hold-and-Spin Basics, With Bull Rush as the Model
A hold-and-spin round swaps the regular reels for a grid of individual cells. Prize symbols that land stay fixed in place, while the empty cells keep spinning for a limited number of attempts. A fresh hit usually refills that attempt counter.
Bull Rush follows that template closely. Its Bull Blitz grid holds 15 positions and the counter starts at 3 Bonus Games. From that point only three symbols matter on the grid: Bull, Silver Coin and Gold Coin.
The Six-Bull Trigger
Bull Blitz starts when 6 or more Bull symbols land in a single spin. The bull like https://bullrush.bet/ turns up only as a trigger symbol and has no entry in the line paytable. Its charge across the middle reels is what opens the feature.
At the moment of the trigger, the Bulls that started the feature keep their spots. Every position that isn't already a Bull becomes a separate spinning reel cell. With exactly six Bulls in place, nine open cells remain on the 15-position grid.
The same trigger works inside the Free Game Feature. If 6 or more Bulls land during one of the 5 free games, Bull Blitz opens there too. Bet size and paylines carry over unchanged from the spin that launched the free games.
Locked Coins and the Three-Game Counter
Each Bull that lands during a Bonus Game converts into a Silver Coin. That coin reveals one of five outcomes: Mega Jackpot, Maxi Bonus, Major Bonus, Mini Bonus or a smaller credit prize.
Coins already on the grid stay locked between Bonus Games, so the board fills up gradually. Maxi, Major and Mini prizes hold their cells as Gold Coins until a new Bull lands or the feature ends.
The counter logic is where the round lives or dies. Landing 1 or more Bulls during an active Bonus Game pays every Gold Coin prize on the grid immediately. The same hit resets the Bonus Game counter back to 3.
- Bull Blitz opens with 3 Bonus Games and the trigger Bulls in place.
- The open cells spin once per Bonus Game.
- A landed Bull becomes a Silver Coin, pays all Gold Coins on the grid and resets the counter to 3.
- The feature ends when the Bonus Games run out or all 15 positions fill.
Filling Up to 15 Positions on the Bull Rush Grid
The feature closes on whichever comes first: the counter hitting zero, or a full grid. A full grid ends the round early, but it also sets up the biggest prize in the game.
Because each Bull resets the counter, a Bull Rush round with steady Bull hits keeps running while cells close one by one. Three Bonus Games in a row without a Bull end it, however many coins are locked.
Up to 5 Maxi Bonus prizes can occupy the grid at once. That is the highest concentration of value the feature allows in a single pass.
Jackpot Tiers and Their Bet-per-Line Values
Every Silver and Gold Coin prize reveals one of five tiers, and each value scales from the bet per line. Bull Rush uses 50 fixed lines, so the bet per line equals the total stake divided by 50.
| Tier | Value | In total bets | At a $50 spin ($1 per line) | Grid behaviour |
|---|---|---|---|---|
| Mega Jackpot | Jackpot prize | n/a | n/a | Pays on reveal; cell resets to the smallest credit prize |
| Maxi Bonus | 10,000× bet per line | 200× | $10,000 | Holds as a Gold Coin |
| Major Bonus | 5,000× bet per line | 100× | $5,000 | Holds as a Gold Coin |
| Mini Bonus | 1,000× bet per line | 20× | $1,000 | Holds as a Gold Coin |
| Credit prize | Smaller credit amount | n/a | n/a | Revealed from a Silver Coin |
Converting to total bet makes the tiers easier to compare. A Maxi Bonus equals 200× the total bet, a Major 100× and a Mini 20×. Five Maxi coins on one grid add up to 1,000× the total bet.
The site lists the Bull Rush max win at 2,500x+ bet. Two jackpot tiers, Mega and Grand, pay outside the fixed Maxi, Major and Mini ladder.
How the Grand and Mega Jackpots Pay
The Grand Jackpot pays when all 15 Bull Blitz positions fill with Silver Coins, Gold Coins and Bull symbols. The fill has to land by the end of a Bonus Game. It is the single largest prize this pokie can award.
A second route exists as well. The Grand can land at random at the close of any paid spin, regardless of how full the grid is at that moment.
The Mega Jackpot follows its own rule. It pays the instant it is revealed, and its cell then resets to the smallest available credit prize. Mega can surface during Bull Blitz or during an X-Tra Hit chain.
X-Tra Hit: A Feature Inside the Feature
X-Tra Hit can only fire inside an active Bonus Game within Bull Blitz. It needs 2 or more Bulls on screen at once, and the reels stop turning while it plays out.
One Bull converts to a Silver Coin, a second becomes the X-TRA HIT symbol and any remaining Bulls hold their positions. Every X-TRA HIT symbol on the grid pays out all current Gold Coin prizes at once.
After it resolves, the X-TRA HIT symbol turns into a Silver Coin with a fresh prize reveal, provided a free position remains. Extra Bulls landing afterward can start the chain again. In Bull Rush, one Bonus Game can run through several X-Tra Hit activations in a row.
What Bull Blitz Means for Bull Rush Volatility
Bull Rush returns around 96% RTP, with high volatility tied to the hold-and-spin mechanic. Big wins cluster around Maxi Bonus runs and Grand Jackpot hits at the end of a packed feature.
Stakes run from $0.50 to $30,000 per spin, and every tier scales with the bet per line. Starting at the minimum and running the demo first shows how the 15-position grid fills before real funds go in.
