Only 1 color per line

Players lay down a horizontal line of color blocks in response to a sequence of colors appearing above them. Each new color in the sequence must match the color of the last block in a player's line. The goal is to accurately replicate the sequence to clear as many lines as possible. If a player successfully replicates a sequence, it expands, requiring the player to repeat the colors in the new sequence, which continues to grow. The game runs in a web browser, requiring no download or registration. Eliminating lines allows for additional space, increasing the length of the new color sequences.
