Pamplona Smash: Bull Runner is a free racing game developed by Rayamedia for the Android platform. It is a game that allows you to experience the famous San Fermin 'Running with the Bulls' festival in Spain. The game is all about being the bull and charging through the streets of Pamplona while knocking the runners out of the way.

The game has several features that make it exciting to play. You can power up the bull by knocking the runners out of the way, and filling the smash meter will let you charge around and be 'invinsibull'. A hat will give you a single chance to keep playing, but it's game over if you hit an obstacle, wall or the smash meter empties. The game also has a new mode called Political Smash, where you can dominate the world.

Overall, Pamplona Smash: Bull Runner is a fun and exciting racing game that allows you to experience the thrill of the famous San Fermin 'Running with the Bulls' festival in Spain. It's a great game for those who love racing games and want to try something new and different.
