The player can configure the game's colour palette, window scaling, and windowed/fullscreen mode. The game ends if the rotation centre of a piece locks above the top of the screen.ĭespite claims about a reprogrammed random algorithm ( "so that you never get a long piece when you need one"), the randomizer is memoryless, same as the original. The next piece spawns immediately there is no lock delay. As in Stack the aim is to get as many pieces into the playfield before topping out, and for each piece placed without topping out the player scores 100 points.Īs with the previous game, pieces lock when they touch any part of the stack, at which point they fall freely. In Invade Mode each player's pieces can move to the other half of the screen after locking (but not while being dropped). Invade Mode is a variant of Stack Mode purely for 2 players.

In 2-player mode player 2's pieces sequence is player 1's sequence mirrored. This can be played in 1-player or 2-player modes. For each piece placed without topping out the player scores 100 points. The aim is to fit as many pieces as possible into the playfield before topping out. Stack Mode brings back the gameplay from the original Not Tetris. This means that density is less important for multiple line clears compared to singles. Where density is the average number of blocks per cleared line divided by 10. Scoring is based both on the number of lines cleared and on the block density of the lines cleared (but not on the current level). As a result, it is possible to clear more than 4 lines at once. Line clears are only checked at the moment a piece locks (when it touches the stack). These fragments will then fall by gravity. When lines are cleared, only the portions of the pieces that are inside the line are removed, causing the pieces to be sliced if necessary. Every 10 lines advances the game's level, increasing the falling speed of pieces.Ī line is considered cleared if it contains at least 8.1 blocks, or slightly under 80% full (as lines in this mode are 10.25 blocks wide). Normal mode has gameplay similar to conventional Tetris, in that the player must try to clear lines in order to survive.
