Perfect Diamond

Perfect Diamond is a fast-paced puzzle game made for the original NES. You guide sliding pieces into a grid to complete and clear diagonal lines, earning points in single-player modes or competing against a friend or the CPU in local multiplayer.

Place and clear pieces

Pieces move forward automatically. You can shift them left or right and rotate them in either direction. When a piece reaches a position where it fits, it drops into the grid. If it passes the grid without dropping, it is discarded and returns two pieces later; if that same piece passes the grid a second time, the game ends.

Completing a line in either diagonal clears it and awards points. You earn additional points for clearing multiple lines at once, clearing lines in both diagonals simultaneously, and fitting a piece snugly into a hole.

Single-player modes

Choose from three modes:

• Survival: Score as many points as possible while the speed increases every 11 lines.
• Prudence: Take your time and score as many points as possible with 250 pieces.
• Velocity: Clear 50 lines as quickly as possible, with score disregarded.

Local multiplayer

Play against a friend or the CPU in three modes:

• Blocks: Score points to send blocks that disrupt your opponent's grid.
• Speed: Clear 11 lines to increase your opponent's speed.
• Both: Play with Blocks and Speed enabled together.
