Klondike Solitaire with a 4-colour card deck

[WillLem]

A 4-colour deck consists of Black Spades, Red Hearts, Blue Diamonds and Green Clubs:



This site provides a way to play normal Klondike Solitaire using this deck.

However, I'd like to program a version which allows the cards to be placed on each other such that any suit can be placed on any other suit, since the cards are all different colours; red and black is no longer relevant here.

Question, though: would this even work as a viable, playable game, or would it become too trivial? What other tweaks would need to be made to the rules?

Sure. It's still a playable game, just with a higher percentage of winnable deals. Card solitaires vary widely from winnable deals being common to very rare without this making any of them "less playable"; FreeCell, for example, has a very high percentage of winnable deals, but the player still has to win them!

That's what I was hoping. Should be worth pursuing, then!

Every move that's legal in regular Solitaire (assuming Klondike, although this likely generalises to most Solitaires) remains legal in this variant; it just allows some additional moves too. So, any deal that is possible under standard (two color deck) rules is also solvable under this, but some additional deals will likely become solvable too. The "Vegas style" scoring in particular would be a bit easier, I'd suspect.
