UNO H2O Splash is a board game released in 2005 for 2–10 players, 30 minutes per game, and ages 7 and up. Its main mechanics are Hand Management and Pattern Recognition.
This version of UNO includes transparent, waterproof cards similar to UNO H2O and a special Whirlpool device. The Whirlpool has random effects that appear when shook (it works like a Magic 8-Ball). The rules are simplified. For example, the winner conditions are no longer points based. The first player to win three hands wins the game. Also gone are rules regarding playing Wild Draw 4 Cards when you can play another card. The Whirlpool is activated by playing a special Splash card or playing a 0 or a 2. The next player must then shake the Whirlpool and follow the results: 1) Draw H2O - draw until they get a blue, 2, 0 or wild card. 2) Wave Right - show a card to the player on the right. 3) Wave Left - show a card to the player on the left. 4) Wipeout - reverse order of play (player who started the Splash must use the whirlpool) Other possible Whirlpool results are draw, discard and give cards. The cards and Whirlpool are contained in a sturdy plastic box, with a slide on/off lid.
UNO H2O Splash supports 2–10 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for UNO H2O Splash is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists UNO H2O Splash for ages 7 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
UNO H2O Splash has a complexity rating of 1.5 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
UNO H2O Splash belongs to these categories: Card Game and Children's Game. Its main mechanics are Hand Management and Pattern Recognition.

The catalogue lists UNO H2O Splash as a base game. It can be played on its own with the components in the box and does not require any other title. Expansions, if any exist, add new content or rules on top of it and are listed separately in the catalogue with a link back to this base game.
