In the mind game Iromeku you have make sure that the colored blocks in the large field are positioned exactly as the blocks at the bottom left. You can do so by dragging small blocks towards the big ones. When a small block touches a big one, the color of the big one changes. Several combinations and changes are possible: try and consider everything so that you get the right color combination! The 'Color Guide' can give you some hints about the colors: maybe worth a try! When you have the right colors, you can click on 'Submit'! Good luck!
