Crisis on the Right: Plancenoit 1815 is a two player wargame at the division/brigade level simulating the struggle that took place near the village of Plancenoit as part of larger Battle of Waterloo. The game puts the Prussian IV Corps against Napoleons right flank and rear units.

The game is played over 12 turns in which players rally troops, place reinforcements, bombard their opponent, move troops, and conduct combat.

Victory is determined by control of key areas and number of troops activated. Napoleon wanted to save as many men as possible for his main fight against the Allied forces so the Prussian player earns victory points based on how many of Napoleon's troops are activated.

The advance of the Prussian IV Corps led by Bulow threatened the French right flank and rear near the town of Plancenoit during the battle of Waterloo. Napoleon was forced to take much-needed troops from his front against the Allies under Wellington to hold back Bulow. In effect, he traded men for time. Crisis on the Right: Plancenoit 1815 is a tactical simulation of those events on Sunday, June 18, 1815.
