EastFront: The War in Russia 1941-45 is a block wargame by Columbia Games simulating the Eastern Front of World War II. Instead of traditional cardboard counters, the game uses wooden blocks that stand upright, hiding unit strength from the opponent (fog of war). Players control either the Axis (Germany and allies) or the Soviet Union, managing production, supply, movement, and combat across a detailed map of Eastern Europe and Russia. The game won the James F. Dunnigan Award for Best Playability & Design and the Charles S. Roberts Award for Best World War II Board Game in 1991.
Each game turn represents two months. A turn consists of:
Both sides produce new units and reinforcements based on their production capacity. The Axis production is relatively fixed while Soviet production grows as the war progresses. New units are placed in appropriate production centers.
Check supply for all units. Units must trace a supply line back to a supply source (typically a home edge or major city). Unsupplied units suffer attrition and reduced effectiveness. Supply lines can be cut by enemy units.
Players alternate moving groups of units. Movement is hex-to-hex across the map. Movement allowances depend on unit type, terrain, weather, and season (mud and winter severely restrict movement). Rail movement allows rapid redeployment along intact rail lines.
Battles occur when opposing units occupy the same area. Combat is resolved using dice, with each unit rolling a number of dice equal to its current strength. Hits are scored based on the unit’s combat value. Defenders typically fire first. Combat continues in rounds until one side retreats or is eliminated.
In certain scenarios, the German player may conduct additional movement and combat, representing the Wehrmacht’s blitzkrieg doctrine.
Blocks stand upright, hiding their identity and strength from the opponent. The top edge shows the current strength (number of steps). When a block takes a hit, it is rotated to show reduced strength. This fog of war mechanic is the game’s signature feature.
Optional rules cover strategic bombing of production centers and partisan activity behind Axis lines.
Victory conditions are scenario-specific:
Turns: Each represents 2 months
Phases: Production > Supply > Movement > Combat > (Blitz)
Fog of war: Blocks stand upright; opponent cannot see unit identity or strength
Combat: Roll dice per strength step; hits on combat value or less; defender fires first
Supply: Trace line to supply source; unsupplied units suffer attrition
Weather: Mud/winter restrict movement; winter favors Soviets
Win condition: Scenario-specific territorial objectives
