Pete Lockwood released a poker game for Nintendo DS.

Tired of the horrendous poker games available for the DS (all flashy graphics and lousy functionality) I decided to write my own.

The whole driver behind wanting to play on the DS was to be able to play poker at lunchtime in an office environment, where cards and chips might be frowned upon 😀

The game currently supports No-Limit Texas Hold-Em for up to 6 players in wireless multiplayer mode or a 6 player Hold-Em or Omaha Hi ‘standalone’ mode where you play all 6 hands (good for debugging and kinda interesting as a simulator).
