Click on two adjacent gems to swop their positions.
To score, align at least three gems of the same colour and shape and the row or column disappears.
Bejeweled is not an uncommon game - it is available as a download for the Xbox and even as an in-game add-on in World Of Warcraft.
The twist in this version, found as an application on Facebook, is that you have precisely one minute to rack up as many points as possible.
Hence, the name Blitz.
As it is in Facebook, it is easy to compete with friends as scores are saved to your user account and compared against those who have also added the application.
As with all Bejeweled games, the intrigue factor is enhanced by "cascading" gems which fall to fill any gaps created by chained gems, resulting in an entirely different placement of baubles on the board.
A player who can think quickly enough to foresee the effects of his gem-swopping will fare better than one who cannot - all within the minute, of course.
Sushi Go Round
(www.miniclip.com)
One of the many games on popular website Miniclip, Sushi Go Round is simple but addictive.
Simulating the stress of working in a sushi parlour, it calls for a fine balance of speed and accuracy.
Customers convey their wishes via images hovering in thought bubbles.
Preparing an order is a matter of clicking on a recipe book to find out the relevant ingredients, selecting them from a tray and rolling them into a sushi for a completed dish.
A satisfied customer will snag you points.
Take too long or serve him something he did not ask for, though, and your eatery's reputation will suffer.
Easy enough so far.
As more and more customers appear, each one making different orders, your imperfect memory of the recipes either results in service that is timely but erroneous, or accurate but infuriatingly slow.
Serve sake to your disgruntled customers to temporarily placate them if you are failing miserably but remember that time is of the essence.
The Truth Is Up There
(www.orisinal.com)
This game is just one of 60 flash games that can be found only on the parent website.
Just click on the correct thumbnail to start playing.
The premise is simple: Shoot a flying saucer using a "camcorder".
Your score depends on how smooth and detailed a video recording you make of the orb in the sky.
Train your camcorder on the object when it appears and follow as it streaks across a cloud-filled cerulean sky by moving the mouse.
You will score more points if you can zoom in on the flying saucer without it moving outside the view finder.
The main challenge lies in getting a consistent recording without being overly ambitious when it comes to its quality.
