About Perfect Diamond

Perfect Diamond is a fast-paced puzzle game created for the original NES from the 1980s. Slide puzzle blocks into the grid to fill lines. Play any of the 3 single-player game modes, or battle a friend or CPU in local multiplayer.ROM file included for those who want to play on emulator or on a real NES via flash cart. (Right-click the game in your Steam library, click Properties/Installed Files/Browse)Mechanics:
  • Pieces slide forward on their own. You can move them right or left, and spin them in either direction.
  • When a piece reaches a position where it fits, it drops into the grid.
  • If a piece passes the grid without dropping into it, it is discarded and comes back 2 pieces later. If the same piece passes the grid a second time, it's game over.
  • When a line in either diagonal is filled, it is cleared and points are awarded.
  • Additional points are awarded for clearing multiple lines simultaneously, clearing lines in both diagonals simultaneously, and fitting a piece snugly into a hole.
Single Player Game Modes:
  • Survival: Try to score as many points as you can while the speed increases ever 11 lines.
  • Prudence: Take it slow and get as many points as you can with 250 pieces.
  • Velocity: Disregard score, clear 50 lines as fast as possible!
Multiplayer Game Modes:
  • Blocks: Score points to send blocks to mess up your opponent's grid.
  • Speed: Clear 11 lines to increase your opponent's speed.
  • Both: Enable Blocks and Speed together.

This game is absolutely outstanding. I play it about 2-3 times a week as it really brings back the nostalgia of old puzzle games from the NES era. If you're a fan of games like Tetris, Dr. Mario, Columns, etc. you'll really enjoy this fun twist on the genre. The different game modes are challenging even for an experienced puzzle player, and it's fun to learn the new approaches and patterns to get the highest score you can. Having an actual NES ROM come with the game is also a pretty cool bonus!
