Wibbell++ is a game system: a deck of cards, each with a pair of letters, a border pattern, and a value. As of 2021, it is known as the ELL deck.

The first edition deck launched with five featured games included and each 1st August sees a new headline game available for free online.

The are eleven headline games currently:

Name	Description	Minutes	Players	Designer
Wibbell	A speedy word game. Shout out words that contain particular letters. As you collect more cards, the game becomes more difficult until the end of the round. Extra obligations give everyone else a chance to catch up.	10-30	3-7	Bez
Phrasell	The party game of inventing little phrases.	20-30	4-10	Bez
Grabell	A speedy game of pattern recognition & dexterity.	2-3	2-7	Bez
Alphabeticell	Assembling an alphabetical sequence. Deciding when to take and when to say no.	5-10	3-7	Andrew Dennison
Faybell	A co-operative storytelling activity. Cards provide inspiration for 'story elements' then let you influence the players after you.	15-30	2-5	Bez
Coupell	Helping your partner make longer words and staying in balance.	30-45	2	Bez
Mickell/Muckell	A true multiplayer solitaire game wherein you work on 3 words at once.	15-30	1-∞	Bez
\|Categorickell	A mental recall/tug of war for 2 teams.	5-15	2-6	Tom Coldron
\|Unfinishabell	Avoiding ever actually finishing a word.	10-20	2	Paul Mansfield

Each year, there is an annual game design contest for the deck, with a deadline of July 31st. In 2023, the winner will get £100 cash, a bundle of games, 12 hrs of Bez's time (to help with anything), and a table at UKGE to show off their game. Everyone will get guaranteed feedback. The hope is that this will continue to be a source of 'headline' games for the deck, meaning that anyone who buys the deck will have an endless source of entertainment.

Additional rules are on the website.
