In this game, the player is a toothpaste tube, and there are eight teeth to defend. Various types of food, such as hamburgers and french fries try to take out the teeth. The player fires toothpaste at food intent on destroying the teeth. If the food is allowed to touch a tooth, it begins breaking down the tooth. If the player is fast enough to shoot the piece of food as soon as it starts breaking down the tooth the player will be able
to save the tooth. If not, the tooth will be broken down. The food comes in waves, and the movements become more complicated. Destroying the food scores points, as does the number of teeth left at the end of each wave, and the amount of toothpaste.
After a certain amount of points is scored, users gain bonus teeth. Bonus teeth are applied at the end of each wave. If all eight teeth are still present, the additional teeth will be placed on the sides of the mouth. Otherwise the teeth will replace any teeth lost. Play continues until all the teeth are gone, at which point the game is over.
Seaquest is an underwater shooter in which the player controls a submarine. Enemies include sharks and enemy submarines. The player must ward off the enemies while trying to rescue divers swimming through the water. The sub can hold up to eight divers at a time. Each time the player resurfaces, all rescued divers are emptied out in exchange for points. To add to the challenge, the submarine has a limited amount of oxygen. The player must surface often in order to replenish the oxygen, but if the player resurfaces without any rescued divers, they will lose a life. If the player resurfaces with the maximum amount of divers, they will gain bonus points for the subs remaining oxygen. Each time the player surfaces, the games difficulty increases. As the game gets more difficult, the enemies increase in number and speed. Eventually an enemy sub will begin patrolling the surface, leaving the player without a safe haven.
Game modes include a single player mode, or an alternating two player mode.
Ice Hockey is a game of two-on-two ice hockey. One player on each team is the goalie, and the other plays offensive (although, the goalie is not confined to the goal). As in the real sport, the object of the game is to take control of the puck and shoot it into the opposing goal to score points. When the puck is in player control, it moves left and right along the blade of the hockey stick. The puck can be shot at any of 32 angles, depending on the position of the puck when it’s shot.
Human players take control of the skater in control of (or closest to) the puck. The puck can be stolen from its holder; shots can also be blocked by the blade of the hockey stick.
The player must pilot a biplane through a series of barns in the shortest time possible while dodging windmills, weather vanes, and geese. Bumping into anything slows down the plane for a couple of seconds, increasing the overall time.
There are four levels of play determined by the game select switch. Game 1 is HedgeHopper (10 barns), game 2 is Crop Duster (15 barns), game 3 is Stunt Pilot (15 barns), and game 4 is Flying Ace (25 barns). In the first three games, the course layout of barns, windmills, and even geese do not change, making it easy to memorize the layout. Game 4 is the only game with a random course.
One or two players control chickens who can be made to run across a ten lane highway filled with traffic in an effort to “get to the other side.” Every time a chicken gets across a point is earned for that player. If hit by a car, a chicken is forced back either slightly, or pushed back to the bottom of the screen, depending on what difficulty the switch is set to. The winner of a two player game is the player who has scored the most points in the two minutes, sixteen seconds allotted. The chickens are only allowed to move up or down. A cluck sound is heard when a chicken is struck by a car.
Viewing from a top-down perspective, the player flies a fighter jet over the River of No Return in a raid behind enemy lines.
The player scores points for shooting enemy tankers (30 pts), helicopters (60 pts), fuel depots (80 pts), jets (100 pts), bridges (500 pts), and (in non-Atari 2600 versions of the game) hot air balloons (60 pts). The jet refuels when it flies over a fuel depot. A bridge marks the end of a game level.
The player’s jet crashes if it collides with the riverbank or an enemy craft. In non-Atari 2600 versions of the game, tanks alongside the river also fire at the player’s jet. If the player’s jet runs out of fuel, it crashes. Assuming fuel can be replenished, and if the player evades damage, gameplay is essentially unlimited.
Unlike later scrolling shooters, there is little or no enemy fire in River Raid. Also, the player’s jet cannot maneuver up and down the screen, only left and right. It can, however, accelerate and decelerate.
