Donkey Kong Junior (US)

Donkey Kong Junior (c) 08/1982 Nintendo.

Something of a role reversal for this superb sequel to the seminal 1981 platform-based original, with Mario now cast as the villain (the only Mario game in which this occurred) and Donkey Kong the captured victim.

Donkey Kong's son, DK Junior, must rescue his captured father from Mario's clutches by climbing and jumping his way over vines, chains and platform before he can reach his father. Junior has to race against time while avoiding the horrible Snap jaws and birds released by Mario.

Like the original, Donkey Kong Junior features four different screens, but the first and second screens are repeated before the final two screens are reached.

* Slow Down : This trick is not really useful but it has a comical effect. On the first level, climb to the top of the two vines at the far right edge of the screen. Then, with one hand on each vine, push up against the top of the screen and hold the joystick forward. All of the action on the screen will slow to snail's pace until you release the joystick.

* Infinite Play : This trick allows player 1 to earn an infinite number of extra turns, at the expense of player 2's game. Player 1 just plays a normal game but each time player 2 has a turn he must perform a trick that costs him that turn and earns each player an extra turn. If player 2 can do the trick every time, player 1 will always have extra turns to play with and player 2 will always have at least one turn left to perform the trick the next time around. At the beginning of the first level, Junior appears on a platform in the lower left corner of the screen, as shown above. Walk to the right edge of this platform, and move as far right as possible without falling off. Only Junior's heel should still be on the platform. Wait at the edge of the platform and watch for a blue Snapjaw to come down the first vine to the right. As soon as the Snapjaw leaves the end of the vine to fall in the water, jump toward him. You should hit the Snap jaw at the same time it hits the water. If you timed your jump correctly, your turn will be over but both players will be awarded an extra turn. You can then play normally (as player 1) until player 2's turn comes up again and you must repeat the trick.
