These flags of the world are a nightmare for any Kobadoo player. Although not two flags of sovereign countries that are exactly the same, they might just differ slightly in colour shades. This is the case of Chad and Romania, where the blue tone of Chad's flag is a bit deeper. These similarities were the cause of an alleged dispute between the two countries in 2004. Moldova and Andorra share the same three colours, but they have a differentiating coat of arms in the center.
Monaco and Indonesia have different tones of red and dimension ratios. The flag of Poland has the same horizontal stripes, but reversed.
You have to be very observant to notice the difference between the flags of Ivory Coast and Ireland.
It might be a bit easier to distinguish the flags of Niger and India, that have the same three colours in more differentiating tones and a circle in the center.
Senegal and Mali are two former French colonies that, together with Cameroon and Guinea, combine green, gold and red vertical stripes in their official flags.
