The first hand-held computer games

I remember in the 1980s, some of my school friends had this little hand-held computer game, where you controlled a man with a mallet who moved from side to side, and you had to get him in the right place to hit these moles on the head as they came up from the ground.

Does anyone else remember that game??

 

I have a hand held FOOTBALL game! (Sadly not my original Green one I got in the 80s (Its white but exactly the same))

 

I don't remember that game but I had a little mermaid hand held game
& some kind of generic Tetris game that sucked.
