Luckily, if you're a fan of Flash – in particular the animations and games it was used to create – the Internet Archive is making sure you can revisit everything that made the early web weird, wild, and where Flash games were concerned, extremely juvenile.
Flash thrives in simplicity, which is why games like Helicopter are some of the best examples of how Flash games can go right. Helicopter is a side-scrolling obstacle game that tasks players with navigating a helicopter through a tunnel without crashing. The format of Helicopter is repeated in more mobile games that you can count and was an early precursor of just how addicting and lucrative the objective "don't hit things" can really be.
Frogger might not be a flash game in origin, but it makes this list for the same reason dozens of other Flash ports might. Flash games brought the joy of retro classics to web browsers everywhere, often adding their own twist to create something new or at the very least, something tongue-in-cheek enough to capture our attention.
Remember the good ol' days? Where all it took to have fun was a swath of bubble wrap and an opposable thumb? Putting Bubble Wrap on this list is admittedly a liberal interpretation of the word "game", but if you're judging Flash products by their simplicity and ability to create dopamine in every click, well, Bubble Wrap is a shoe-in.
