Hop up the trail. Mind the wagons, ride the logs, and don't let the dust catch you.
Hoppy Trails is an endless crossing game seen from above. A jackrabbit, a wagon road with traffic on it, a river carrying logs, a level crossing with a train due, and exactly one direction that counts for anything. You hop forward until something stops you. That is the whole game, and it is enough, because every obstacle in it is a timing problem with a right answer and a very short window in which to find it.
What makes it a game rather than a queue is that waiting is not free. A few seconds in, a wall of dust starts moving up the trail behind you and it never stops. Stand on a safe strip long enough to be certain of the gap and the dust takes the decision away from you; go on the first gap you see and the gap is usually a wagon. Every run is that argument, held about two hundred times.
The one-way crossing game is one of the oldest arcade forms there is: a hazard that moves across your path on a fixed rhythm, a safe strip between each one, and a player who can only really go forwards. Cabinets were built on it in the early 1980s and the shape has outlived every generation of hardware since, for the same reason noughts and crosses outlived the slate — it needs no story and no tutorial. You learn the rules by dying to each of them once.
What the modern versions added was endlessness. There is no level to clear and no top of the screen: the trail keeps generating ahead of you, the traffic gets denser and faster the further up it you get, and the score is simply how far you went before it caught you. It turns a puzzle with a solution into a habit with a personal best.
Distance pays coins, and it pays them unevenly on purpose: every row is worth something, rows past the first stretch are worth more, and rows deep into a long run are worth more again. Quitting early and starting over is always the worst way to earn, which is the point — the game would rather you got better than that you played more.
There are ten characters and every one after the first three is held by two locks at once: a price in coins, and a best single run long enough to have earned it. A full purse buys nothing on its own. The later ones want distances you will not reach by accident, and one of the ten is not for sale at any price — it is out there, and that is all this page is going to say about it.
