How wins work

  • The board has 5 reels × 3 rows and 20 fixed lines. 3 or more matching symbols from the leftmost reel pay; the slugger is wild and appears on reels 2–5 only.
  • The four corners of the frame are the bases: first base bottom right, second top right, third top left, home bottom left. A runner carries cash (×0.5–×25 the total bet in the base game) and takes first base when it lands; whoever is on first is forced to the next base, and with the bases loaded the runner on third is forced home.
  • A hit carries an advance (+1, +2, +3, +4; +4 is a home run). After every runner has taken a base, everyone on base moves forward by the spin's total advance.
  • Runners who reach home plate pay their cash; each base-game spin starts with empty bases, and runners left on base pay nothing.

Paytable

Values are total-bet multiples for one line: line win = total bet × table value. The slugger (wild) appears on reels 2–5 only and substitutes for regular symbols. Runners and hits do not form lines; the cash they bring home is paid separately. These are the same values shown in game.

Special symbols

Slugger

Wild. Reels 2–5 only; substitutes for regular symbols, not for cheer flags, runners or hits.

Cheer flag

Scatter. No connection required: 3 or more start extra innings; 3 during the feature add 3 innings.

Runner

Lands carrying cash and takes first base. Pays only when it reaches home; in extra innings it stays on base and inning k pays ×k.

Hit

Carries an advance (+1, +2, +3, +4). After every runner has taken a base, everyone on base moves forward by the spin's total advance.

Features

Base running

Runners and hits are the heart of the game: get on base, move up, and only a trip home pays. When several runners score in one spin they come home one by one, and each amount slams into the win capsule.

Extra innings

Cheer flags: 3/4/5 → 8/10/12 innings; 3 during the feature add 3 innings. One spin is one inning, runners stay on base for the whole feature, and cash brought home in inning k pays ×k (added innings keep counting up). Runners in extra innings carry ×0.5–×5.

Grand slam

If all three bases are occupied after the runners take their bases and the spin's total advance is 4 or more, it's a grand slam: the runners pushed home pay another ×4. The later the inning, the bigger it gets.

Home run derby

Any base-game spin can open the home run derby: 5 swings, each paying by distance (100–145 m = ×10–×14.5), ×50 for a ball out of the park, nothing for a miss — and a ball that hits the outfield billboard pays ×7,000 outright. Both the production engine and the independent simulation actually reach the 7,000× cap.

Volatility and win distribution

RTP 96.59%, volatility 5.50. These rates use complete rounds started by a regular bet, including naturally triggered extra innings; bonus buys are counted separately. The 28.28% hit rate counts any winning round; 18.82% of all rounds return at least the stake. Maximum win is 7,000× the bet per round.

Buy extra innings

Pay 32.376× the bet to start 8 innings of extra innings (bonus-buy RTP 96.59%), priced from the expected value of the purchase route.

The story

Fiction and adapted settings written by Akitsora Gaming for this title, including invented dialogue and events. This is not a historical or folklore reference. The rules and specification tables define the gameplay and math.

Bottom of the ninth under a clear sky, every seat in the stands packed tight,
as the catcher flashes the sign and the whole stadium watches the pitcher's glove.

I. Stepping Onto the Four Corner Bases

Brass bands blare from the packed bleachers under a bright summer sky, and the freshly watered dirt of the infield gleams around four white bags. The four corners of the reel frame are the baseball diamond itself: first base sits at the bottom right, second at the top right, third at the top left, and home plate at the bottom left. Banners flutter in the warm stadium breeze while the crowd claps in rhythm with the brass section in the stands.

Every runner symbol lands on the reels carrying a cash prize and sprints straight to first base, forcing any teammate already on base one bag ahead around the frame. If all three bases are already occupied, one more runner walks in a run and forces the runner on third home. Watching runners round the corners of the reel frame turns every spin into a live inning on the diamond.

II. Driving the Runners Home with a Hit

In baseball, reaching base is only half the journey — a run only counts when a runner touches home plate. Once every runner on the spin has taken a bag, the hit symbols step up to the plate, adding up singles, doubles, triples, and four-base home runs into a combined advance. The crack of the wooden bat echoes across the infield as the ball streaks past the diving shortstop into the outfield grass.

Every runner standing on the diamond sprints forward by that combined advance, slamming their cash prize into the scoreboard one by one as they cross home plate. In the base game each spin begins with empty bases, so runners left stranded on the bags do not score. When several runners cross the plate on the same big hit, they charge home one after another to the roar of the crowd.

III. Extra Innings and the Grand Slam

When enough cheer flags wave across the reels, a tied ballgame heads into Extra Innings. Here every spin counts as a new inning on the scoreboard, runners stay on base from inning to inning instead of clearing, and every runner who crosses home plate multiplies their cash prize by the current inning number. Stadium floodlights blaze against the evening sky as the tension builds with every runner held on the bags.

Best of all, if all three bases are loaded with runners after they take their bags and the spin's hits add up to four or more bases, the batter unleashes a Grand Slam — multiplying the payout of every runner driven home on that swing. Clearing the loaded bases with one towering swing is the moment every fan in the bleachers waits to see.

IV. Sunset Swings and the Outfield Billboard

On any base spin, the stadium lights can flare against a crimson sunset for the Home Run Derby. The slugger steps into the batter's box for a set of big swings, where each ball launched into the bleachers pays by its flight distance in metres — and a shot clear out of the park pays even more. White baseballs arc high into the twilight sky while the distance meter climbs with every crack of the slugger's bat.

Towering above the distant outfield wall beside the scoreboard stands a golden billboard. Drive a baseball straight into that outfield sign with a ringing clang, and the entire stadium rises to its feet as the derby awards its top jackpot prize outright. From a bases-loaded walk-off to a billboard-rattling blast, the ballpark echoes with the thrill of a championship night.
