“Quad” here means SPI’s quadrigame boxes: four stand-alone games sharing (usually) a common core ruleset, plus short “exclusive rules” per battle.
Blue & Gray (SPI, 1975)
SPI’s breakthrough quadrigame: four American Civil War battles at a digestible footprint, tuned for “learn one, play four.” It’s the template that made the format famous: clean IGO-UGO, decisive CRT-driven combat, and just enough battle-specific chrome to keep each map distinct.
What battles are in the box?
- Shiloh
- Antietam
- Cemetery Hill (Gettysburg)
- Chickamauga
How it plays
Expect classic hex-and-counter maneuver with “commitment” friction from Zones of Control and attritional CRT outcomes. The design sweet spot is teaching operational thinking (lines, key terrain, timing) without the overhead of monster-CW systems.
Edition note: TSR reprinted some SPI quads after acquiring SPI; Blue & Gray is commonly seen as an SPI/TSR boxed reprint. (You’ll often find both on the secondary market.)
Modern Battles: Four Contemporary Conflicts (SPI, 1975)
The “modern” quad that mixes real recent history with plausible Cold War hypotheticals. Two games depict Yom Kippur War actions; two go full “what if?”—which makes this set less thematically unified, but often more replayable.
Included battles / conflicts
- Chinese Farm (Yom Kippur War)
- Golan (Yom Kippur War)
- Wurzburg (hypothetical Warsaw Pact vs NATO)
- Mukden (hypothetical Soviet incursion into Manchuria)
How it plays
Tight IGO-UGO tempo with zones of control, artillery and air as headline levers, and a “combined arms without a PhD” vibe. Combat is CRT-driven; the fun is in timing fires, pinning, and exploitation rather than chrome-heavy doctrine simulation.
Scale note: BGG’s description frames this as 1 mile per hex, 12 hours per turn, with unit sizes ranging from battalion to brigade.
Napoleon at War: Four Battles (SPI, 1975)
The Napoleonic quad is often remembered as a “gold standard” of the early run: four major engagements, common core rules, and enough differentiation (especially in the larger Leipzig situation) to keep veterans interested.
Included battles
- Marengo (1800)
- Jena-Auerstadt (1806)
- Wagram (1809)
- The Battle of Nations / Leipzig (1813)
How it plays
A straightforward IGO-UGO battlefield system: maneuver, bring mass to bear, and manage cohesion/tempo with minimal overhead. Combat is CRT-based and the tactical “story” emerges from lines, reserves, and the timing of decisive attacks.
Scale varies slightly by battle (Leipzig is often treated at a broader map scale than the others).
Island War: Four Pacific Battles (SPI, 1975)
A Pacific ground-combat quad spanning the war’s arc: Guadalcanal through Okinawa. It’s not “tactical skirmish”; it’s an operational-ish battle game where geography, tempo, and attrition do the talking.
Included battles
- Bloody Ridge (Guadalcanal)
- Saipan
- Leyte
- Okinawa
How it plays
The system emphasizes pressure and endurance: pushing inland, grinding down fortified positions, and managing lines. CRT combat is the engine; “chrome” often focuses on Pacific-specific behavior (e.g., banzai-style attacks in many summaries).
Blue & Gray II: Four American Civil War Battles (SPI, 1975)
The sequel doubles down: same approachable core with four new battles, and (importantly) a built-in “mini-campaign” linkage for two of them. If you love the system but want different operational problems, this is the natural next stop.
Included battles
- Fredericksburg
- Hooker and Lee (Chancellorsville)
- Chattanooga
- Battle of the Wilderness
How it plays
Same IGO-UGO heartbeat and CRT combat, but with more variety in terrain and operational constraints. The ability to combine Fredericksburg and Hooker & Lee into a campaign format is a big value-add if you like narrative continuity.
Thirty Years War: Four Battles (SPI, 1976)
Early-modern warfare through an SPI quad lens: compact battles, a shared rule core, and a surprisingly “close” scale for the period. If you like formations and timing but don’t want a simulation brick, this is a fascinating artifact—and occasionally a very good game.
Included battles
- Freiburg
- Lützen
- Nördlingen
- Rocroi
How it plays
CRT combat plus positional play. The interest comes from the period constraints (command friction, formations, and the geometry of battle), expressed in a streamlined 1970s style.
Westwall: Four Battles to Germany (SPI, 1976)
For many players, the WWII quad: four late-war Western Front battles under one umbrella. Westwall’s best scenarios capture the “operational squeeze” of 1944–45—limited daylight, chokepoints, and the brutal arithmetic of time.
Included battles
- Arnhem (Market Garden)
- Bastogne
- Hürtgen Forest
- Remagen
How it plays
Operational-level maneuver and timing: sealing pockets, forcing river lines, and concentrating force at decisive crossings. CRT combat does the heavy lifting; the memorable moments come from “can I get there in time?” tension rather than chrome complexity.
Decision Games describes its modern Westwall edition as an operational battalion/regiment simulation of these battles.
Four Battles in North Africa (SPI, 1976)
Desert warfare distilled into four compact operational battles. The quad is often praised for value—lots of scenarios, clear objectives, and a core system that keeps the focus on movement, supply pressure, and decisive armored thrusts.
Included battles
- Crusader (Tobruk relief)
- Cauldron (Gazala)
- Kasserine
- Supercharge (El Alamein)
How it plays
IGO-UGO with rigid ZOCs and CRT combat, plus the “desert extras” (artillery/air support in many summaries). The best sessions feel like a race between operational opportunity and positional collapse.
Napoleon’s Last Battles (SPI, 1976)
Waterloo as a quad—then a campaign. Each battle is playable on its own, but the signature trick is that the maps interlock, letting you fight the whole 1815 campaign as a linked operational narrative.
Included battles
- Quatre Bras
- Ligny
- Wavre
- La Belle Alliance (Waterloo)
How it plays
CRT-driven Napoleonic combat with a strong “where is the decisive point?” feel. The combined campaign format elevates the set: you get operational choices (concentration, delay, commitment) that single-battle games can’t always provide.
TSR also published editions of Napoleon’s Last Battles after the SPI acquisition; Decision Games has a modern “SPI Update” edition.
Modern Battles II: Four Contemporary Conflicts (SPI, 1977)
A sequel conceptually similar to Modern Battles, but structured around one historical fight (Jerusalem 1967) and three hypothetical flashpoints reflecting late-1970s anxieties. It’s a time capsule—and a useful one if you enjoy “period doctrine” hypotheticals.
Included conflicts
- Jerusalem 1967 (Six-Day War)
- Bundeswehr (hypothetical West Germany)
- DMZ (hypothetical Korea)
- Yugoslavia (hypothetical Balkan conflict)
How it plays
Expect the same broad family feel as Modern Battles: CRT combat, significant fire-support levers, and brisk IGO-UGO turns. The variety is the appeal; the downside is that “one ruleset fits all” can flatten doctrinal differences.
Four Battles from the Crimean War (SPI, 1978)
The Sevastopol campaign as four linked historical moments. This is a great example of SPI using the quad format to explore an under-gamed conflict without demanding a huge commitment from the player.
Included battles
- Alma
- Balaclava
- Inkerman
- Tchernaya
How it plays
CRT combat with a comparatively “old-school” feel. The hook is variety: each battle’s terrain and objectives force different operational priorities, even though the shared rules keep onboarding quick.
Battles for the Ardennes (SPI, 1978)
A quad spanning the Ardennes as both the German “first breath” of 1940 and “last gasp” of 1944—excellent thematic coherence. It’s also a set with a reputation for rules issues in early printings, which makes edition/errata awareness part of the hobby experience.
Included battles
- Celles
- Clervaux
- Sedan
- St. Vith
How it plays
Operational tempo and constraint. CRT combat resolves fights quickly, and the larger lesson is about timing: when to punch through, when to hold, and how to avoid overextension in terrain that loves chokepoints.
The Great War in the East: Four World War I Battles (SPI, 1978)
A WWI quad that deliberately avoids “the Western Front trench stereotype.” Instead you get mobile, supply-sensitive operations where command range and unit quality differentiation actually matter—surprisingly modern design instincts for the era.
Included battles
- Serbia/Galicia
- Von Hindenburg in Poland
- The Brusilov Offensive
- Caporetto, 1917
How it plays
Still IGO-UGO and CRT-based, but with added operational friction: supply and HQ command distance constrain movement and attack. A “tactical efficiency” rating differentiates formations beyond raw combat strength, which can make the game feel less like an odds puzzle and more like an army puzzle.
Publication-date note: some SPI quad lists show later catalog dates for certain titles; Wikipedia and many hobby references place this quad in 1978.
Four Battles of Army Group South (SPI, 1979)
Late-run quad design: bigger operational canvas, more varied time scales, and a system lineage tied to classic WWII operational play. If you like Eastern Front operational dilemmas without a monster commitment, this one is worth hunting.
Included battles
- Kiev (1941)
- Rostov (1941)
- Operation Star (1943)
- Korsun (1944)
How it plays
Operational movement and positional combat, CRT-driven, with emphasis on tempo (armored exploitation often appears in summaries of the system family). Each battle’s time scale shifts the feel: some are sharp “encirclement problems,” others longer operational grind.
The Art of Siege: Four Great Siege Battles (SPI, 1979)
The odd duck—and proudly so. Many SPI quads share a common rules engine; this one is widely described as “mixed systems” with different scales per siege. That makes it less of a teaching tool, more of a curated museum of siege problems.
Included sieges
- Tyre
- Acre
- Lille
- Sevastopol
How it plays
More chrome and asymmetry than the average quad. That’s the appeal—sieges demand engineering, logistics, and time pressure— but it also means clarity and “system mastery” aren’t as smooth as in the classic shared-engine quads.
Great Medieval Battles (SPI, 1979)
Medieval battlefields are hard to model simply without turning them into generic shove-fests. This quad tries: it keeps complexity down, but still aims to reflect the period’s “shock and cohesion” dynamics through its combat procedures.
Included battles
- King Arthur (Camlann, mythical framing)
- Robert at Bannockburn (1314)
- The Black Prince (Navarrete, 1367)
- Tamburlaine the Great (Ankara/Angorra, 1402)
How it plays
A tactical CRT-driven system with many dice touches. The upside is immediacy; the downside is that medieval nuance can be subtle, and a quad system sometimes can’t spotlight each battle’s unique character as sharply as a bespoke design.
