Tanks are certainly one of the most incredible machine created by the visionary mind of Leonardo da Vinci. He designed this project more than 400 years before the first tank was actually built, during WW I.

Tanks are very likely the most powerful weapon you can use when playing Magnifico because a single tank can have the same firepower of an entire army of infantry men, and you can use up to 6 tanks in a single battle. Although they can be almost useless against a well fortified target, in the very first stage of the game they are essential for conquering many territories, but they don't works averytime as you can expect.
When you use a tank, you must roll up to 6 dice and check if "something is going wrong". The only one thing you care are the "explosions" (on every die there is the symbol of an explosion on one side). To work at it's maximum firepower a tank need no explosions so it's quite easy to understand that the more dice you roll the more chance you get to produce at least a single explosion. A single explosion means the tank's working at just half power, two explosions mean the loss of the tank (if you are using the highly suggested optional rules) and three explosions mean the loss of the tank and of all of your infantry men. This is a real disaster, so it's very important to know the odds.

While it's really easy to calculate the chance to produce a specific event rolling a single die, when you roll two or more dice the odds can be surprisingly different to the expected ones. In the chart below we have summarized the percentages to get at least one, two or three explosions depending on the number of dice rolled.

Use it wisely to improve your strategy when playing Magnifico.
