Tidalis is a block-based puzzle game with casual appeal, hardcore depth, and an addictive new "streams" mechanic. The basic rules of the game are this: blocks fall down into the board and have a color and an arrow direction. If a stack of blocks exceeds the height of the board, you lose. In order to clear blocks, you must right-click and drag paths through the arrows to set up chain reactions of like-colored blocks.
Your PC will need a graphics card thats as powerful as a GeForce 2 MX 100/200 32MB/Rage 128 Ultra 16MB and it should be paired with either a Athlon XP 1800+/Pentium 4 1.8GHz CPU to match the Tidalis recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. 1 GB will also be needed to achieve the Tidalis rec specs and get 60FPS. Make sure your GPU can run DirectX 9 or Tidalis won’t run. We suggest a 18 year old PC to play smoothly.
