Frog Hopper

Josie wanted to remake Frogger. The original arcade game came out in 1981, designed by Konami, and it's one of those games that everyone has heard of but most modern kids have never actually played. Cross a busy highway, then cross a river by hopping on logs and turtle-backs, then settle the frog into one of five home spots at the top of the screen. Repeat five times to clear the level. Watch out for the snake, the alligator, and the lady frog you sometimes have to escort across.

The mechanics translate to the browser without any drama. Five lanes of traffic in different directions and speeds, a median strip, then five lanes of river with logs scrolling across. The frog hops one tile at a time. If you touch a car you die. If you fall in the water you die. If you make it home you score points. There is no levelling system, no upgrade tree, no mid-run cutscene. You play, you die, you try again.

What surprised Josie when she started building it was how much the original game's feel depends on the hop animation. The arcade Frogger doesn't actually animate the frog smoothly between tiles — it just snaps. But the brief flicker between positions, plus the satisfying audio click, makes each hop feel decisive. Without that micro-feedback, the game feels mushy. She spent more time tuning the hop timing than on the actual gameplay logic.

How to be good at it. Pattern recognition. Each level has a fixed traffic configuration; if you watch the highway for a few seconds before you start crossing, you'll see the gaps repeat. Time your first hop into the gap and the rest of the road follows. The river is harder because the logs and turtles are continuously scrolling — you have to keep moving with them or you'll be carried off the edge. Turtles dive periodically; don't trust one for more than a couple of seconds. The home slots reward speed; you get bonus points for clearing the level quickly.

Build notes. The lane system is just a fixed-speed sprite scroller per lane. Collision uses simple AABB tests against the frog's hitbox, which is intentionally a little smaller than the visible sprite — this is one of those subtle game-feel decisions where being technically generous makes the player feel they were being skilled. Forty-year-old game designers figured out all of these tricks decades ago, and they all still work. If you enjoy the timing-and-pattern feel, try Jazz Ball for a similar arcade remake with a more strategic twist.
