Olaf & Elmar (whose full name is Olaf & Elmar in the Castles of Nabokos) is a game featuring some nice characters: an elephant and a mouse. The objective of the game is practically identical to that of the famous Sokoban.
Only this variant of Sokoban is somewhat different, because Olaf (the elephant) can push large blocks of stone, while Elmar (the mouse) can only push small stones. Therefore, you will have to push, move and place each of the stones in their corresponding place, without any of them blocking any exit or other stones.
Of course, as you advance in level in Olaf & Elmar the puzzles of stones to be solved will be increasingly complicated; Fortunately, at least you have unlimited time to solve each of these puzzles.
You can free download Olaf 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
