N-is: A Generalized Tetris Game

N-is is a terminal-based puzzle game that generalizes the classic Tetris concept to work with polyominos and polykings of any size from 1 to 6 blocks. Play traditional Tetris (4 blocks) or experiment with Tris (3 blocks), Dis (2 blocks), Pentis (5 blocks), or even Hexis (6 blocks)! Made for Sumer of Making

Features

• Flexible Block Size: Choose your game style with different block counts:

  • 1: "Monois" (single blocks)
  • 2: "Dis" (domino shapes)
  • 3: "Tris" (triomino shapes)
  • 4: "Tetris" (classic tetromino shapes)
  • 5: "Pentis" (pentomino shapes - more challenging)
  • 6: "Hexis" (hexomino shapes - extremely challenging, nearly unplayable)

  Heptis will probably never be made because even hexis is not very fun, and heptis just simply has no reason to exist.

• Interactive Menu System: Run without arguments to access a user-friendly curses-based menu for selecting game options

• Extended Mode: Enable with -e flag to add non-standard polyominos (polykings) that can connect at vertices

• Mix Mode: Enable with -m flag to include polyominos of lower order (e.g., in Tetris mode, also get Tris, Dis and monois pieces)

• Advanced Gameplay Features:

  • Hold System: Hold pieces for later use with 'c' key
  • Ghost Piece: See where your piece will land
  • Hard Drop: Instantly drop pieces with Enter key
  • Combo System: Chain line clears for bonus points

  • Fall speed increases with each level by around 14.5%
  • Scoring system with level and combo multipliers
