Pettson’s Inventions Deluxe is a unique and highly engaging problem solving puzzle app for children as well as adults.

Meet Pettson and his cat Findus, and help them build fantastical contraptions while keeping in mind the laws of physics as players add different parts to the machine-like cogs and belts as well as unique items such as a ramp made out of cheese or a flower pot.

It is tempting to compare Pettson’s Intentions to a Rube Goldberg machine, and although I think this comparison has some merit, I do not believe it is spot-on as Rube Goldberg device solve simple daily problems such as turning on a light switch with the use of a convoluted and over-built invention. Here, however, there is more of a sense of nonsense as one may devise a way to open and close monster cages as the creatures when loose may scare an animal making it run, pulling a lever behind them, watering flowers to make them instantly grow which may lure a cow to graze, as well as tasks that could include washing a pig or making it snow around the house with the use of an ice cream cone and a windmill.

This deluxe app consists of the content of Pettson’s inventions 1 and 2 and includes six new puzzles as well as the ability to race the clock to play against someone as the screen of the iPad is then split and users play head-to-head on the same device.

It is worth noting that this app has a few really important options, as one can get a visual hint of how to solve the problem at hand by not just being told the object, but by also seeing a visual clue allowing users to see what it looks like to make a dragon happy instead of just hearing the description. Another option is to having only the parts needed for the specific invention or including other items that will not be needed for the puzzle, thus increasing the difficulty of these sections.

When ready to work on these puzzles, one will note that certain clues are given throughout, as pins to attach gears may be included, or there may already be gears within the invention that one needs to attach a belt to as well as pipes in need of being fitted or pulleys which take shape when dragged onto the invention area of the page, center screen, as all the items to be used in these contraptions can be seen lining the perimeter of the page.

As one becomes more familiar with these puzzles, the tools one can add to the inventions will become more familiar as they work consistently the same way from puzzle to puzzle, also noting that there is some color coding that is also included – a nice touch.

I also appreciate how the power to these inventions can be turned on while building to see how the plans are working so far, allowing players to see what more needs to be done.

For the most part, I find the level of difficulty in this app good, and I have been able to solve the majority of these puzzles on my own without too much frustration.

It is nice to know that one can find walk-throughs of much of this app on line if needed, as I did for a scene where one needs to suspend a weight in mid air, and I could not find the sweet spot from which to hang the anvil. It would be nice if the app had help like this within the app as well for children who may feel stuck.

Pettson’s Inventions Deluxe is a wonderful app for logic and problem solving. The inventions one creates are highly creative, and I am quite fond of all the quirky details found within.
