Well, I don't think I remember much of the other unlockable games, as mine was glitched out and i had to reset it. WARNING: Never put dead batteries in a TamaProfy. It's okay if the batteries DIE in the thing, just dont do that. I got a Giragiratchi named 0000 and I couldn't play with anything, the games were not unlocked as the games that were built-in instead of unlocked.
50pts = 1 Tama Heart
100pts = 2 Tama Hearts
(etc. on and on and on.)
Gypsytchi's Fortune Telling - I don't really think it's a game, it's more of just a chance thing. you tap the icon and you either get a giant crystal, a small one or some poop. (which is more rare than the crystals.) If you scroll down, you can read your fortune. (?)
Tama Heart Power Meter - You choose 2 characters and it shows the kizuna bond between the two.
Melody Rhyme - Repeat what Melodytchi sings. I think the game goes on for about 1 minute.
Dokidoki Fishing - Whenever the little thing that bobs up and down goes down completly, tap the screen and you will see it say, "GET!". Keep tapping rapidly and you will reel in the fish.
Jewel Get - You have to tap the jewel whenever they pop up.
Kuchi Jump - Jump over the obstacles before Kuchipatchi hits the obstacle. It gets harder and harder overtime. (This is a unlockable game.)
TamaMori Catch - You need to know Japanese to play this one. Look at the bottom of the screen. It shows what group of Tama Heart you need to get. Catch the TamaMori that is inside the group to get a point. It also goes faster overtime. (This is a unlockable game.)
Plant Pickup - Same with Jewel Get, but with Memetchi and jewels replaced by plants. (This is a unlockable game.)
Chama ABC Catch - Same with TamaMori Catch, but with Chamametchi and TamaMori replaced by letters. (This is a unlockable game.)
These are all I know for now.
