Operation Barbarossa is a highly rated turn based strategy game set on the Eastern Front during the Second World War. From Joni Nuutinen: By a wargamer for the wargamers since 2011. Latest version out on March 2026.

You are in command of the German WWII armed forces—tanks, infantry, and air force units—and the object of the game is to conquer the Soviet Union as quickly as possible. To have a chance to seize the top spot in the Hall of Fame, you need to skillfully encircle scores of Red Army infantry units with your panzers while battling both the feared T-34 tank units and the notorious Russian weather.

The fairly small scale of the map means you can't really make any big mistakes if you're aiming for the top spots in the Hall of Fame, as the battle-hardened players have been grinding this game for a decade.

FEATURES:

+ Limited scale, so turns advance quickly.

+ Historical accuracy: Campaign mirrors the historical setup.

+ Long-lasting: Thanks to in-built variation and the game's smart AI technology, each game provides a unique war gaming experience.

+ Reinforcements and replacement units, plus new unit types - like Tiger I tanks - if the war lasts several years.

+ Experienced units learn new skills, like improved attack or defense performance, extra move points, damage resistance, ability to cross rivers without losing move points, etc.

+ Settings: Various options are available to alter the look of the gaming experience: Change difficulty level, hexagon size, Animation speed, choose icon set for units (NATO or REAL) and cities (Round, Shield, Square, block of houses), decide what is drawn on the map, and much more.

+ A large range of WWII units under your command: famous German panzer divisions, infantry, motorized infantry, weak Axis infantry, the German air force and espionage units. Meanwhile, the Red Army starts with weaker infantry, cavalry and tank units, but as the weeks pass, is reinforced with stronger Siberian and T-34 tank units.

+ Weather modelling: Spring/autumn mud slows movement, while winter reduces line-of-sight and freezing cold hampers units, especially mechanized ones.

Conflict-Series by Joni Nuutinen has offered highly rated Android-only strategy board games since 2011, and even the first scenarios are still actively updated. The campaigns are based on the time-tested gaming mechanics TBS (turn-based strategy) enthusiasts are familiar with from both the classic PC war games and legendary tabletop board games. I want to thank the fans for all the well thought-out suggestions over the years which have allowed these campaigns to improve at a much higher rate than what any solo indie developer could dream of. If you have advice on how to improve this board game series please use email, this way we can have a constructive back and forth chat without the limits of the store's comment system. In addition, because I have huge number of projects on multiple stores, it’s just not sensible to spend handful of hours each day going through hundreds of pages spread all over the Internet to see if there is a question somewhere -- just send me an email and I will get back to you. Thanks for understanding!
