Shanghai

Each player has to proceed for score around the board from 1 through 20 and then bull's-eye. Throw 3 darts for each number and the player who gets the most scores wins. On the appropriate Arachnid Electronic Dart Board, there are 3 levels of difficulty and player can score at any right segments (single x1, Double x2, Triple x3) for L level; and only double or triple will count for X level.

Also players can select super Shanghai (P Level) as a complementary option. The rules are the same as above except various doubles and triples must be hit as specified by the computer. The computer will display the chosen "double" or "triple" and display the number at the scrolling screen.
