There are exactly 100 levels to get through to erbuild the place. After that it's possible to replay each board separately.
This game has three different game modes which can be changed each level. This alone should make it interesting but I found that only the swap mode is enjoyable at all.
At first there's only an option to shuffle game pieces, then 4 power-ups are gradually added. They build on one another with only one of them being available at any one time. They can't be taken from one level to another so might as well be used. There's also a bonus piece if you match 5 which will pop 2 pieces atop, below, left and right.
What kept me from giving 4 stars is the feeling that there were too many levels depending on excessive use of the power-ups thus forcing one to just keep on playing with no other goal than to collect enough power for the power-up needed. This was especially the case in higher levels which is why I think shorter might have been better.
Btw, this game is actually by Green Sauce Games and they offer the successor themselves.

This game is more in the line of the classic point & click adventures than the HOG it's classed to be, including all the walking between locations.
The puzzles are interesting but as a tipp, it really helps to read the info first and try and figure it out after. They can be skipped, too, and I admit that I did towards the end. The HOG scenes are well done - and if a location came up twice the objects I picked up the first time around were not there again so that was very realistic. If you are not a native speaker, keep a dictionary handy (reading „bat" I think of an animal, but it can also be connected with sports).
This is certainly a game to play again one day; I'm sure there's still a lot to discover. The storyline is fun and imaginative, too.

Total game time for 1 quest: 7 hours.
I generally like M3-Games if they can be played without a timer and yet stay challenging. This one can. Objects have to moved away from walls or blocking bricks, frozen tiles must be melted or they won't move, 4 different types of power-ups collected... It also tells a sensible story along the way about Hercules.
Levels are usually 4 M3, 1 HOG, 4 M3, 1 replace-the-artifacts and another HOG. Neither could be skipped but neither was too difficult either. I hardly ever needed hints.
The game tells me I can now embark on another quest with "new challenges and obstacles" but I won't just now.
If you liked „Around the World in 80 Days" but were frustrated by the time pressure than this game might be for you.
