小天使(1293)-儿子的sudoku 游戏

打印 被阅读次数

家里订了份报纸,其实并没多大用--老爸看新闻多是上网,老妈呢,也就是看看电视。不过,报纸上每天的sudoku游戏很不错,老爸和女儿经常是边吃晚饭边讨论,惹得不懂怎么玩的儿子心痒痒的,求了老爸几回,让老爸教他怎么玩。试着讲了几回,儿子也没完全理会,就没当回事了。

报纸上的sudoku是分级的,从周一的第一级到礼拜天的第五级。女儿对一到三级是不屑一顾的。昨天回家,一看是简单的第一级,老爸突然心血来潮,想花点时间,好好教教儿子,看他的逻辑思维如何,也让他有一些逻辑训练。所以,父子俩吃完晚饭,把桌子收拾干净,就开始儿子的第一次sudoku游戏。

规则简单,花了2分钟,儿子就知道了。不过,要他真正懂,老爸还得陪着他填几个数字。儿子不错嘛,5分钟就会自己用排除法来筛选数字了。老爸就让他自己作,偶尔指点一下,没半个小时,居然让他把一个puzzle解决了。小人儿一激动,拿起报纸就去找姐姐和老妈:“See, I can do it now! I figured out this puzzle by myself!”

今天老爸一下班,儿子已经自己在家作开了。今天是level 2,难度要大些。儿子让姐姐和老爸别出声,他自己作。呵呵,还满入迷的,连饭也忘了往嘴里送。人小,不是忘了“横”向(row)看, 就是忘了“竖”向(column)看。老爸稍微提醒一下,偶儿问问儿子的思路,看样子还不笨。半个小时就让他全解决了。姐姐看了一下,居然没错呢。

老爸对女儿说:“Your brother is not bad at all. I guess after you go to college, I can discuss with him.”

老爸儿子终于找到“共同语言”了。
