Every day Wordo travels to a different country. You have 6 attempts to discover where he is. If a letter in your guess matches a letter in the correct country (regardless of the position), its tile will be green. If it doesn’t, it will be brown. Additionally, after each attempt, you will see a hint: a tile showing the distance* and direction** between your guess and the correct country.
In the following example, "Guyana" contains two "A"s and only one turns green, meaning that the correct country (Greenland) has only one "A".
* Distances are calculated based on the approx center of both countries.
** Direction is calculated using a simplified version of the azimuth formula. It might not always be very precise or intuitive, specially on long distances.
