What is BOGGLE?

I looked BOGGLE up in many places and for many times, but I haven't got anything important. So I wrote an email and asked for Barbara's help.
" Boggle is a game using dice. These cubes usually have numbers on the sides but in Boggle each side has a letter. A player rolls the dice and then has a limited time - a timer is included, I think it's 2 minutes - to write down as many words as possible using the letters displayed. Players take turns and the winner is the one who has written the most words after a set number of tries. You could probably make some dice with heavy paper. Kids love this game."
You help me so much, dear Barbara. Thank you so much.
How's your mother now? I hope you and your mother have a good winter.

BOGGLE的玩法：用硬纸卡自制一个骰子。骰子的六个面分别写上六个字母而不是数字。轮流投掷。在规定时间内（如2分钟）写出含有某个字母的单词。多次投掷后，将写出的单词相加，总数多者赢。孩子是很喜欢这类游戏的。
