It opens very easily and when open can stay that way until the puzzle is done. When your done you can slid it under the bed.

We live in an assisted living  housing. My wife would go to a jigsaw puzzle room, which has one of your puzzle wheels.  I talked her into buying one for our suite. Now she doesn't have to leave out room to work on her puzzle. It is very well built, we are enjoying it. (It will probably outlast us.)

I purchased this based on simplicity and price as a gift for my brother-in-law in his early 30s. It did not look impressive coming out of the box, however once I began to try putting the pieces back in the square the challenge began. It is essentially a puzzle, with several ways to put the puzzle together so it creates a square. It is small, so it travels well and comes in quite handly during those inevitable moments of boredom.

This is one of the easier 500-piece puzzles that I've done. Each building and element is pretty easily discernable from the others. The pieces fit tightly together so if you like to build seperate sections and then move them into place, this works well for that. One irritation for me that may not bother you at all is that there is  no unoccluded picture of the puzzle. The one on the box has a few areas covered (not much but enough to bother me), and the picture in the box has 20-some labels on the buildings that cover much of the detail.

These puzzles are very addicting and fun to solve.  Good exercise for your mind.  I would recommend it for filling free time.

Overall, it's pretty addictive and interesting.

I have enjoyed doing jigsaw puzzles for years.  This handy dandy little item has made it even more enjoyable.  I usually leave all the pieces in the bottom of the box, pick out the end pieces, and then just shuffle through the remaining pieces inside of the box while I look for particular ones.  With the Sort and Go, I pick out my end pieces and put them all in one tray, then depending on the puzzle, I pick out all sky pieces and put them in one tray, or maybe all the flowers into a tray, or all the water pieces into a tray...etc.  And now that I've taken just a few minutes to sort all the pieces into their perspective categories, I no longer have to hunt for pieces inside the box.  I like the stacking feature also, in that I can store the trays away and save space because they stack right on top of each other with the pieces still in them.  This is a great gift for someone if they enjoy doing jigsaw puzzles.

My class loves trying to solve the puzzles. We use is at the end of class or you could use it as a bellringer

Fun puzzles. A bit repetitive, but each different, thus solving one won't help you solve another. They are all basically the same type of puzzle though. There looks to be another math type, but haven't tried those yet. These take my husband and I quite a while to solve. They make a fun way to pass the time and exercise your brain at the same time. We probably won't ever use all 12 of these books, let alone two, because one puzzle seems to take us around an hour. They aren't easy, and I'm sure are good for your brain.

It's pretty entertaining when people scoff at this square puzzle then struggle to finish it. The only problem is, these puzzlesites are less skill and more trial and error.

I work for a security company, and I often find myself in the middle of nowhere with nothing to look at and nobody to talk to. This makes falling asleep a serious risk, as in a risk to my employment and potentially a risk to the people and property I'm protecting. How do I avoid this problem? Playing games like this.

As you wander the village trying to solve various mysteries, people keeping challenging you to solve various puzzles they give you. I must admit, sometimes, all you want to do is enjoy solving the mysteries and the number of puzzles you have to deal with at times can be annoying once in a while, it keeps your brain active, and the puzzles range from easy but makes you feel smarter for knowing the answer so fast all the way to spending far more time then you would ever expected it would take to solve a puzzle in a game rated E for everyone. The cover makes the game look childish, but take my word for it, it keeps adults guessing too.

It was worth every penny to buy this game.

I love this kind of puzzle activity and enjoy the process of discerning the minute differences between each of the pieces. I often pull Pajaggle off the shelf to play solo, simply as a means of keeping my brain sharp. A timer is included, so you can race the clock to beat your previous best time if you like. My five year-old also enjoys the puzzle aspect of Pajaggle and it is great for developing his visual perception skills. We do own an additional set of pieces in a different colour, which can be used to go head to head with another person while using just one board (count up who has placed the most pieces at the end of the round to see who has won), but I do think that if this is the kind of activity that members of your group truly enjoy, that having an extra game board and pieces in a different colour works best.

This is a conveniently sized and challenging crossword puzzle book to have on hand if one is traveling, or in waiting rooms. I do not think all of the puzzles qualify as actual "brain twisters", but most of the puzzles are worth solving.

Perfect. Beware with the puzzles with knobs you can fit as many.

The puzzle was challenging and took about 12 hours spread out over 4 days. However, I ended up being one short of 1000. Also, the cutting of the prices could be a little more precise and have a better fit. Going to attempt to fill in the missing piece and mod podge it into a frame.

I do sudoku and cross word puzzles every day to stay sharp. Erasers are a necessity. I ran out, but I won't again.
