Objective of crossy road: The objective is to cross a series of roads, rivers, and other obstacles without getting hit or falling off the screen. The player controls a character that must navigate through the hazards to progress.

Movement: The player can move the character in four directions - up, down, left, and right. 

Obstacles: The game features various obstacles the player must avoid, including:

   - Cars and trucks moving across the roads

   - Trains moving across railroad tracks

   - Rivers with logs and other floating platforms

   - Gaps and holes in the terrain

Scoring: The player earns points by successfully crossing each obstacle and progressing further in the game. The score increases incrementally with each step the character takes.

Death and Respawning: If the character collides with an obstacle or falls off the screen, the player loses and the game ends. The player can then choose to start a new game and try again.

Power-ups and Unlockables: The game features various power-ups and unlockable characters that the player can collect to enhance their gameplay experience.

Endless Mode: Crossy Road is an endless game, meaning there is no defined endpoint or finish line. The game continues indefinitely until the player loses.
