Ready to train your logical puzzle solving skills? Meet DuoLand, a logical puzzle game based on the 4-color math theorem. This theorem says that any region-divided map can be colored so that no 2 adjacent regions share the same color and using only 4 colors. DuoLand is not yet-another-eye-candy puzzle, instead it offers a playful and colorful journey to test your attention, memory and logical reasoning skills.
The purpose of DuoLand is to prove the theorem by coloring all regions so that no 2 adjacent regions would be colored the same. It offers extra help by providing 6 colors in total (not 4). However, the goal is to score as high as possible and score is calculated by multiplying the color points with the region points. 2 of the colors are worth 0 points, thus try to avoid them for a higher score.
- Logic puzzle gameplay. DuoLand features a puzzle gameplay that requires logical skills to solve. The goal is to color all regions on a given map so that no 2 adjacent regions share the same color.
- Two-sided challenge. The play map on DuoLand has 2 sides that must be solved simultaneously to finish the game. This makes it more brain challenging as a color change on one side might change it on the other as well.
- Easy to play. The game starts right after you open it, and you just have to simply tap on a region to change its color. There are 6 colors in total but any map can be solved with 4 colors.
