Triolet Every number counts. Simple to learn, difficult to master - this is a great two-player game - just enough time to finish a bottle of wine between you, whilst playing.
It's great for education as well, with many schools around the country now having Triolet as part of their maths curriculum. Number bonds and addition skills are improved in a non-threatening and fun environment.
In a nutshell - it's like Scrabble® with numbers...
