The restriction in solo mode to 1 move on the first turn, as intended in multiplayer, can have unexpected consequences for players because they will not be able to choose the card that seems most suitable to them on a freshly generated game board, but will be limited to the adjacent card (for the first move, this is a restriction to 3 moves - if adjacent to a black joker - or 4 moves instead of 7). It is really up to the AI to create a generator that evaluates this and determines whether the game board is solvable under these conditions or not. But to apply this rule in real life, when we shuffle 9 or, in the worst case, 16 cards and arrange them randomly, we have no idea whether it is playable under the given conditions.
