Nabogorf is a sokoban game from Hempuli, the developer behind the puzzle title Lorgeban. Both games are similar in the sense that they feature an egg-shaped character and involve pushing blocks to the appropriate locations, which are marked by an X.

Figure everything out yourself

While Lorgeban has regular-looking blocks, the ones in Nabogorf are shaped like frogs and come in two types. One is a black upside-down frog block and the other is a white non-inverted frog-shaped block. However, players will have a tough time figuring out how to move the non-inverted frog. 

If you make a mistake, you can reset the level or undo your last action. The stages are designed to be mind-boggling — but once you figure out how to move the frog-shaped blocks to the correct spots — the flag will rise and you can progress to the next level. 

A tougher puzzle game

If you love Lorgeban and want more intellectually stimulating sokoban titles, Nabogorf will scratch that itch. The latter title is a tough cookie to crack as players are left to figure out the mechanics behind the white non-inverted frog blocks, which may leave them bewildered or frustrated.
