Here is Part 6 in my ongoing series of Mario and Sonic online game recommendations (see also Part 5, which includes a summary of all my previous recommendations). This is a little bit different to the previous parts, as one of my game recommendations actually runs from within this blog post...
Until the first version of the Nintendo GameBoy was released in 1989, early handheld video games were expensive single-game machines with basic LCD displays and simple gameplay - pretty much like the ones that are sometimes given away as free gifts with fast-food meals nowadays. But they were (and still are) great fun to play, due in large part to that very simplicity - they're perfect for short bursts of "boredom relieving". Here are some Flash online recreations of a few of them for you to try:
1982 Nintendo Game & Watch: Donkey Kong Jr.
(Monochrome LCD "Wide Screen" type, Model No. DJ-101)
1983 Nintendo Game & Watch: Donkey Kong II
(Monochrome LCD "Multi Screen" type, Model No. JR-55)
1983 Nintendo Game & Watch: Mario Bros.
(Monochrome LCD "Multi Screen" type, Model No. MW-56)
1983 Nintendo Game & Watch: Mario's Bombs Away
(8-Colour LCD "Panorama Screen" type, Model No. TB-94)
2003 McDonald's Happy Meal Game: Sonic Speedway
(Monochrome LCD Single Screen - included here as a modern-day comparison)
If you haven't already tried it out (I recommended it in Part 5 of this series), here is a Flash recreation of a handheld game that provides a real modern-day comparison with those early handhelds:
2007 Nintendo DS Game: Sonic Rush Adventure
