Game15 will freshen your memory and ingenuity! Moving blocks on the field, you should order their arrangement according to the increase of numbers, beginning from the top left (or construct some picture, depend on ?theme?). You can move several blocks at a time. If you think that it?s too difficult and you can?t solve the problem, change your point of view! Choose from the menu and you are sure to succeed! Show your skills! Do not be afraid of the unsolvable situations! Any time "Hint button" is always accessible to you, by tap and hold it you may see built picture entirely. If it?s too easy for you ? make the task more difficult: increase the size of the playground or add the number of the fixed blocks. Good luck!
