Count Speed 3D is a casual, racing game with endless running, obstacle and physics elements. The player's primary goal is to make certain that their vehicle successfully reaches the end of the racetrack.
As with endless runners, the game propels the vehicle down the track automatically the moment the player interacts with it. The player must perform maneuvers to increase speed, such as launch the vehicle off a ramp or drive it through blue accelerator walls. They must also collect as many coins as possible and prevent the car from hitting obstacles, including red deceleration walls, stacked tires, spiked columns and giant meat cleavers.
The player can earn or buy a wide range of boosters that improve their chances during the race. They might use an acceleration booster or an automatic coin magnet booster. With the latter, they don't have to drive through coins to collect them. Instead, the booster attracts coins to the vehicle as it races down the track. They can even upgrade their vehicle with coins. That said, they must build up an income of several thousand coins to afford upgrades.
Count Speed 3D features a special final achievement test as well. The player must arrive at a rainbow-colored, reward-multiplier section at the end of the track with enough speed for one last burst of acceleration as far as possible down the track to earn extra rewards.
