Game Title

  • QUADSTACK

Project Status

  • Implementation phase
  • Alpha candidate 0.2 available for testing. Feedback is welcome!

Synopsis

  • Test your wits on a Tetris clone that includes all the features you could ask for!
  • 15 regular levels, plus 25 Master levels of increasing (and to be frank ridiculous) difficulty.
  • Implements the Super Rotation System (SRS), meaning all sorts of kicks and spins are possible.
  • T-Spins are scored!

How To Play

  • Tetriminos drop from above; goal is to line them up in such a way that they fill up entire horizontal lines of the board. Such lines get cleared after they are made.
  • Scoring is done based on how many lines are cleared at once as well as the current level. Spinning the T-Tetrimino into hard-to-reach places may grant you more score!
  • Every 10 lines, your level increases, increasing the speed at which your Tetriminos fall, with the highest speed at Level 15 a.k.a. MASTER 0. Further MASTER levels decrease the amount of time you have to move your piece until it locks. Level 40 ("GM") is the end, with pieces instantly locking.
  • The game ends if the next Tetrimino is blocked. You will be ranked based on what level you achieve.
  • Good luck!
  • Joystick
    • Left/Right to move the current Tetrimino
    • Down to make it fall faster ("Soft Drop")
    • Up to make it fall instantly and lock in place ("Hard Drop")
  • Buttons
    • Buttons 4 and 3 rotate the current Tetrimino
    • Button 2 places it in Hold, instead letting you use the Tetrimino that was previously held. You can't put a piece you got from the Hold back in Hold.
    • Button 1 pauses the game. While paused, Button 2 toggles the shadow and Button 3 toggles the NEXT view.
  • In the main menu, Button 1 cycles through levels 1 to M0, while any other button start the game.

Trivia

  • Sounds will be implemented soon.
