What you are looking at when the road loads
The screen shows a chicken on a pavement and a road stretching away from it, divided into lanes. Above each lane is a multiplier, and those multipliers get larger the further out you look. Below the road are your controls: a bet field in virtual coins, a difficulty selector, a button to step forward, and a cash-out button that stays dark until you have taken at least one step.
That is the entire chicken road game. You bet, you step, and each lane you survive raises the multiplier you would collect if you stopped right now. You keep stepping until you decide to stop or until a step ends badly, at which point the round is over and the stake is gone. The genius of the format, and the reason the stake chicken game caught on the way it did, is that the game never pushes you. It just waits, showing you a number you could have, and lets you talk yourself into one more lane.
