◆ 24 BOMBS · THE LIT FUSE · THE POWERBALL ◆

Tehkan's 1984 arcade original — the seed Mighty Bomb Jack grew from. A caped hero floats around a single screen, set against the wonders of the world, defusing twenty-four bombs and chasing the lit fuse for the multiplier while the homing saucers close in. Catalogued into UD0 as a game-world, themed as a 1984 cabinet, rendered from the game rather than invented — and strictly separated from the NES sequel's anti-greed machinery, which the arcade original never had.

The Four Natures

each emergent comes by one of four natures — the living & the places, the lift & the air, the scoring machine & electronic foes, and the chase & the wonders

natural
the living & the places — Jack himself, the birds that drop in, and the earthbound wonders (the German castle, the city skyline) he floats among
ethereal
the lift & the air — Jack's float and glide, the Greek light of the Acropolis, and the famous borrowed music drifting over it all
electrical
the scoring machine & the electronic foes — the 24 bombs, the lit-fuse multiplier, the Powerball, the bonus letters, and the homing flying saucers; the arcade as a system
spiritual
the chase & the wonders — the pure score-hunger of the cabinet, the Sphinx and the platform-less night, the mummies; the soul of the arcade with no story to lean on

The Arc

there is no story — only the loop: the screen → the gamble of the lit fuse → the Powerball & the climb to the next wonder

THE OVERALL ARCBomb Jack has no plot — and that is the point. It is a pure 1984 arcade score-chase: Jack, a caped, floating hero, drops into a single screen set against a famous world landmark and must collect all twenty-four red bombs to clear it. Only one bomb's fuse is lit at a time; grabbing the lit one builds a multiplier worth far more than playing it safe — but chasing it means flying into the path of homing saucers that mean instant death. Fill the bonus meter and a Powerball appears that freezes the enemies into collectable coins. Five backdrops cycle: Egypt, Greece, Germany, a Miami-style skyline, and a platform-less night. There is no story, no demon, no punishment — just the elegant gamble.
I · the screen
twenty-four bombs, one lit

Each round is a single screen of platforms against a wonder of the world, scattered with twenty-four red bombs. One bomb's fuse is lit at any moment. Jack drops in, floating, and the only goal is to collect all twenty-four — but how you collect them is the whole game.

II · the gamble
chase the lit fuse

An unlit bomb is worth 100, safe and dull. The lit bomb is worth 200 times your multiplier — up to 800 — and grabbing a long run of lit bombs in sequence pays a huge end-of-round bonus. But the lit bomb is wherever the danger is, and the flying saucers home in on Jack. Greed for score, not for treasure, is the tension.

III · the Powerball & the climb
freeze them, clear the wonders

Collecting bombs fills a meter; at the top, a bouncing Powerball appears. Grab it and every enemy freezes into a coin worth 100, then 200, on up to 600 — a brief window to cash in. Clear the screen, the backdrop cycles to the next wonder, and the difficulty climbs. No ending cutscene, no rescue: just a higher score and one more screen.

The Score

this game's deep-dive — the pure arcade score-chase, exactly: the 24 bombs and the lit-fuse multiplier (maxing at 23 lit = 50,000), the Powerball's 100–600 ladder, the B/E/S letters, the float, and the famous borrowed music

The 24 Bombs & the Lit Fuse
the multiplier gamble

The whole game in one mechanic. Each screen has 24 red bombs; only one is lit (flashing) at a time, and grabbing it lights the next in sequence. An unlit bomb scores 100; the lit bomb scores 200 times your multiplier (max 4×, so up to 800). The real prize is the end-of-round bonus for collecting lit bombs in a run: 20 lit = 10,000, 21 = 20,000, 22 = 30,000, and 23 = 50,000 — the maximum. (It caps at 23, not 24: because lighting follows collection, the very last bomb can't be taken while lit. Don't believe the 'all 24 lit' myth.)

The Powerball
freeze the enemies

Not a static coin — a bouncing 'P' Powerball. Collecting bombs fills a meter (a lit bomb adds 1, an unlit bomb half a point); at 10 the Powerball appears. Grab it and every enemy on screen freezes, and Jack can fly into them to collect them as coins worth an escalating 100, 200, 300, 400, 500, up to 600 (capped — it does NOT double to 800/1600). A short, frantic window to convert danger into points.

The Bonus Letters
B · E · S

Three special coins cycle in as you score: B (Bonus) raises your score multiplier (up to 5×, though bomb scoring tops out at 4×); E (Extra) grants an extra life; and the rare S (Special) awards a free game. Reading the screen for which coin is worth breaking your bomb route for is part of the expert play.

The Float
jump and glide

Jack doesn't just jump — he floats, controlling his descent and hovering to thread between platforms and incoming saucers. Mastering the glide is how you reach the lit bomb on the dangerous side of the screen and drift back out before the homing enemies converge. Patience and precision, the same control scheme the whole lineage is built on.

The Bootleg Beatles
the licensed-arrangement soundtrack

The wildest true fact: the arcade soundtrack is not original. It's built on arrangements of real songs — one level theme is an arrangement of The Beatles' 'Lady Madonna' (1968), and the first-level theme arranges the ending theme of the 1983 anime Mrs. Pepperpot ('Kittens in the Cornfield'); only a third track is original. The Japanese flyer even carries the JASRAC rights logo. Many modern emulated re-releases quietly replace the music to dodge the licensing — so the Beatles tune is often missing today.

Real or Fluff

the verdict — the real (the Beatles soundtrack, the Elite ports) and the false (no torture room here, no Hawaii backdrop, only Mighty Bomb Jack is Tecmo's sequel, the bonus caps at 23 not 24)

The arcade soundtrack includes The Beatles' 'Lady Madonna'a licensed arrangement (JASRAC on the flyer); the first-level theme arranges a 1983 anime ending; only one track is original — and re-releases often replace the music
REAL
Max bonus is for collecting all 24 bombs while litthe lit-bomb bonus caps at 23 (= 50,000); lighting follows collection, so the 24th can't be taken while lit
FALSE
The Powerball doubles enemy values (200/400/800)the frozen-enemy coins climb 100 → 600 and cap at 600 — no doubling
FALSE
There's a Hawaii / Diamond Head backdropthe five are Egypt (Sphinx & pyramid), Greece (Acropolis), Germany (a Neuschwanstein-style castle), a Miami-style skyline, and a platform-less night street
FALSE
Bomb Jack II and Bomb Jack Twin are Tecmo sequelsonly Mighty Bomb Jack (1986) is Tecmo's; Bomb Jack II (1986) is Elite Systems', and Bomb Jack Twin (1993) is NMK's
FALSE
The arcade game punishes greed with a torture roomthat's the NES sequel, Mighty Bomb Jack — the 1984 arcade original has no story and no punishment; it simply rewards bold collecting
FALSE
Elite's home-computer ports were a big dealElite Systems' 1986 conversions — ZX Spectrum (Crash 92%), C64 (often called the best port), Amstrad CPC — made it a European staple
REAL
It was designed by one personcredited to two designers, Michitaka Tsuruta and Kazutoshi Ueda (Ueda later did Solomon's Key and the sequel)
FALSE
Bottom line: the 1984 arcade Bomb Jack is the pure, storyless seed of everything that followed, and most of what people 'remember' about it is either fuzzy or imported from the NES sequel. There is NO torture room and NO anti-greed punishment here — that moral machinery is Mighty Bomb Jack's invention; the arcade original simply rewards the bold collector who chases the lit fuse for the multiplier while the saucers home in. The numbers are precise (lit-bomb bonus caps at 23 = 50,000; the Powerball coins climb 100→600 and stop), the five backdrops are real wonders of the world (no Hawaii), and only Mighty Bomb Jack is Tecmo's true sequel (II is Elite, Twin is NMK). And the strangest documented truth: you are clearing the Sphinx and the Acropolis to an arrangement of the Beatles' 'Lady Madonna,' licensed and then quietly scrubbed from later re-releases. A perfect, elegant arcade machine — and the origin point of the Bomb Jack lineage.

The Message

what AVAN reads as the game's thesis: the seed, and the tree — a pure dare that its sequel grew into a parable

The 1984 arcade Bomb Jack is the pure thing — no story, no rescue, no demon, no punishment, just the elegant gamble of the lit fuse. Every screen offers you the safe play (the unlit bomb, a flat 100) and the bold one (the lit bomb, worth up to 800 and building toward a 50,000 bonus) — and the bold one is always wherever the homing saucers are. That single tension, repeated against the wonders of the world and scored to a bootleg of the Beatles, is the whole game, and it is enough. What makes it quietly fascinating in hindsight is the contrast with its own sequel: where Mighty Bomb Jack grew a conscience — a torture room that punishes you for grabbing too much — the arcade original has the opposite philosophy. It doesn't moralize about greed; it rewards courage. Same hero, same floating jump, same bombs; opposite souls. The arcade says: be brave, chase the fuse, take the risk. The NES sequel says: want too much and the pyramid will break you. Play them back to back and you can watch a piece of game design grow up — from a pure dare into a parable. The seed, and the tree.

“No story, no punishment — that came later. The 1984 original simply rewards the bold: chase the lit fuse, dodge the saucers, clear the wonders of the world to a stolen Beatles tune. The seed of the whole lineage.”— AVAN's read

The Cast — Jack and the foes

the arcade has no story, so this is its whole 'cast' as ACI .agents — the floating hero and the birds, mummies, orbs, and homing saucers that hunt him; each with its twin sigils and full 5 W's, rendered from the game, not invented (5)

Rendered, not invented. Arcade Bomb Jack is a game with no story — so this world carries no .shadow (no real-world cast), and there is no plot to dramatize: just Jack, the foes, the scoring machine, and five scenic screens. Every emergent is distilled directly from the verified game, with the fan myths corrected in Real-or-Fluff. Note especially: the famous anti-greed torture room is NOT in this arcade original — it belongs to the NES sequel, Mighty Bomb Jack. The seed, and the tree.
