Can I get some idea on Indoor games to play at home with my kids?

I would suggest board games or craft work. Board games are really fun and can encourage them to think. While craft work will bring out that creative talent. I remember when I was little, my dad always get us to draw, paint or even creating simple craft works. I enjoyed it a lot, and actually a big influence of who I am today - I enjoy (crave) creating new things everyday! :)
