This is Tetris exactly as it appeared on the Nintendo Entertainment System in 1989, the version still used at the Classic Tetris World Championship. Seven kinds of blocks fall into a tall well, you slide and spin them so they fill complete rows, and full rows vanish. A-Type is the endless mode where the level rises every ten lines and the pieces fall faster and change color, while B-Type starts you on a pile of random junk blocks and asks you to clear 25 lines. You choose your starting level from 0 to 9, or up to 19 by holding A, and pick one of the classical tracks for background music. Scoring rewards patience: one Tetris of four lines at once is worth 1200 points, far more than four single lines. For more block puzzles, play Block Blast.
The arrow keys work as the NES D-pad: left and right move the piece and down drops it faster. The A and B buttons rotate the piece in each direction (by default on keys such as Z and X, and you can change them in the emulator's control menu), and Enter starts and pauses the game. There is no instant drop or hold slot, so think ahead with the next-piece preview. Keep your stack flat, leave one column empty for the long I-piece, and clear four rows together whenever you can. Pieces get much quicker around level 19, so practice B-Type to learn how to clean up a messy board.
