Puzzle games are great for wasting some time on your Pocket PC and it's always nice to see something new and original to try out.

BlackFlip is an interesting puzzler where your mission is to flip over black and white tiles in order to tile the grid in one color. There are more than 6,000 different grids included in the game each with a different pattern, and a differing difficulty level, from one to five stars (with five being the most difficult).

I found the game a little frustrating at first because it's very difficult to work out exactly what you're supposed to be doing and there are no in-game instructions. After checking out the demo video on the developer's site and experimenting for a bit, I finally worked out the dynamics of the game.

BlackFlip actually proves to be quite engrossing after a while, and the thrill of turning an entire grid white becomes strangely compelling. With so many puzzles included and a Zoom facility to help you out, there's certainly plenty of life in this one. Unfortunately though, I felt some of the difficulty ratings were a bit odd, as some supposed five-star ones I finished very easily, while I puzzled over a few one-star games for ages.

The gameplay is a little convoluted, but once you get the hang of it, BlackFlip becomes an amusing way to pass some time.

Don’t be fooled by the name. Bolts&Nuts is a polished version of games such as Bejewelled, for your Pocket PC.

The nuts and bolts: collect as many points as you can, by swapping neighbouring items (bolts, gears, jewels). To win points you have to create horizontal or vertical sets of 3 identical items. To swap any two adjacent items you choose one item, then a second one, and they will switch places. The two items must be side-by-side. For points you have to create a valid set (line) of three or more identical items with each move. If you aren’t able to do this, the items return to their initial position. But once you’ve successfully created a line, it disappears and new items appear. The more lines you eliminate - the more points you win!

Bolts&Nuts comes in two modes:

• Normal: the game ends when there are no further moves available, but you can take as long as you like to play.
• TimeTrial: you play against time. You have to get through each level within a specified time period.

An interesting puzzle game for your PDA.

Free Swapper is a Pocket PC version of a game that dates back to olden days. It was invented by Tibetan monks and was an integral part of a complex ritual. The game surfaced in the royal courts of France during the XVIII century and quickly became popular among the lords and ladies - and their kids, too.

The concept of the game is straightforward, but attention is required on the player’s part. Legend has it that a certain Tibetan monk (whose name nobody seems to recall) boasted that since he had attained something close to spiritual perfection, he could keep a game of Swapper going forever. The monk managed to continue a game for several days… till he was caught cheating and unceremoniously expelled from the monastery.

Swapper is similar to the game Bejewelled. Swap any two adjacent gems and create a valid set of three or more identical gems with each move. Our Swapper is faithful to the best traditions of such well-known games as Lines, Tetris and other "tile" type games.

The family is in for some good times with Swapper. But please: no monk-ey business.
