Spludlow Tetris

Spludlow Tetris Introduction

A network implementation of Tetris game allowing multiple players connected to a server. The game is played as normal but with the option to “target” other players, so your completed lines are sent to the bottom of their stack.

To send you need to complete more than one line at a time and that many minus one will be sent: 2 sends 1, 3 sends 2, and 4 sends 3.

You can run as many servers where you like:

·         Local Host – Single Computer multiple players on same desktop

·         Local Network – Run the server on your LAN (local network) and play from other computers on the network

·         Internet – Run the server configured to accept connections from the Internet public network

A standard 2 player on one desktop game:

Spludlow Tetris Server Modes

Spludlow Tetris – Standard Mode


Spludlow Tetris – Creative Mode

Here is the server running in “Creative Mode” (use a server tick of 0):

Spludlow Tetris – Battle Royale Mode

In this mode all players play to the death, leaving one player standing at the end who is the winner.

The game is started in standard mode all contenders are given the opportunity to connect to the server, set up their controls, and warm up with a friendly game.

When everyone is ready the “BR” command is sent to the server, this resets all players boards and the match is started.

Players play as in standard mode targeting other players and sending them lines. When a player dies they are removed from the game but stay connected to the server so they can watch the remaining players, by changing the target board.

When only one player is left they are declared the winner and the server returns to standard mode.

Spludlow Tetris – Levels Server Mode (Coming Soon)

The current implementation is pretty much as simple as a multiplayer game can be, keep it simple to start with and build from there.

The new server mode will work like this:

·         Each player is in a level, they start at 0 when they join the server.

·         Levels are progressed by the number of lines sent (say 50), when you send 50 lines you go to level 1

·         Each level will have a faster tick speed (say 50 milliseconds quicker)

·         You can only send lines to players on your level

·         Level 0 will have a maximum number of players (say 50) and not allow additional new connections (until players have progressed out of level 0).

·         Other levels (over 0) will not have player limits.

·         If you die in level 0 you are kicked off the server.

·         If you die from level 1 (maybe higher) or higher you are put in level 0.

This should allow for many players competing against players of similar ability on the same server.

I’ve thought it through, just got to bang the code out.

Version History

00/00/2019 – V1.9

Added Battle Royale Mode

07/12/2018 – V1.8

Rewrite of Spludlow Tetris UI using WPF (Windows Presentation Foundation). All board flicker is now removed and board drawing code simplified, just change colour of rectangles rather than using Graphics to draw directly to form.

Settings are now persisted to files in “C:\Users\%USERNAME%\AppData\Roaming\SpludlowV1\SpludlowTetris” for each running instance. For example if you setup 2 players the target server, display name, window size and position, and input device will already be configured the next time you start 2 instances.

Settings dialogue improved now allows key mappings to be defined easily.

The F2 key will now cycle through input devices to make selection of joystick easy for each instance.

TetrisAudio class thread safety using SharpDX.XAudio2 fixed not waiting for buffer to flush before submitting new buffer, test methods created for extreme loading.

TetrisInput class tweaked for auto-repeat to behave more like the keyboard and fixed to allow input devices to be removed without throwing and exception.

15/10/2018 – V1.7

Initial release.
