Minor chords sound sad , major have strenght. V chords want to resolve to I .

To help recognizing the IV and V chords, you can try to recognise the feeling they bring with them. If a V goes to I it has a stronger cadence than if the IV resolves to the I. The same principle applies back and forth with every chord really. If you go from I to IV it has a specific feeling, compared to going from I to V, you can recognise this by practising a lot and carefully listening to how it sounds. It can also be nice to practise them on piano to go on your own tempo without the added pressure from the game.

okay, thanks so much I'll try it out!
sometimes I feel it but most of the times I can't tell the diff 😞
but how to tell if it's from I-IV-V or I-V-IV is there also a feeling cus I just can't get it right without guessing :(

Do not overthink it 😉. It takes time and patience but it is not that complicated. You just need to get used to the sound/feel/timbre of each chord variation. I also might have the perfect (no pun intended) tip for your second question. Listen to the song Hallelujah (Cohen, Buckley...). There is this line: well it goes like this, the fourth, the fifth... And the progression is I,IV,V so it is perfect for memorizing how it sounds 😀. It helped me personally a lot.

@Petr Hartmann It also has The minor fall, the major lift, with the corresponding chords being the vi and the IV, so it can also help with the first part of the question.

So much collective wisdom here at the Tonegym! Great guidance. For me, one little thing that helps me is listening for common tones between chords. For example, moving from the I to the IV you'll hear one pitch remain the same. Same goes for V to I or I to V. Whereas if you're moving from the IV to the V, there are no pitches in common and you hear every pitch move.

This, in combination with everything else that's been written here, should help you. Keep going!

i don't know either, sorry. most games i am making progress but scales, chords and progressions i am completely stuck at level 1 or 2
