Rubah4d

Rubah4d is a mobile card game centered on solitaire variations, each described with a different card objective or rule. Klondike asks players to build foundation stacks from Ace to King, while Spider focuses on descending card order and clearing the cards. FreeCell deals every card face up, and Patience is presented as another variation with its own rules.

Klondike builds foundations from Ace to King

In Klondike, the stated goal is to build foundation stacks in ascending sequence, starting with an Ace and ending with a King. This gives the mode a clear ordering objective: the foundation cards must follow that rank progression. The description calls it a traditional version and refers to the usual rules, but does not spell out additional card movements or restrictions.

Spider focuses on descending sequences

Spider has a different stated objective: build cards in descending order and clear all cards. The descending sequence rule distinguishes its card arrangement goal from Klondike’s ascending foundations. Clearing all cards is the mode’s described endpoint; the source does not specify additional sequence requirements, suits, or move rules, so those details are not assumed here.

FreeCell deals every card face up

FreeCell is identified by its open deal: every card is face up. The source presents this as a different challenge for experienced players, but does not explain further rules or how cards may be moved. Its documented distinction is therefore the visibility of the full deal, rather than a specific winning sequence.

Patience is a separate rule variation

Patience is listed as another mode with unique rules that challenge strategy and patience. No particular objective or card-order rule is provided for this variation, so it is best understood from the available description as a distinct option rather than a specified sequence puzzle.

Daily challenges add distinct objectives

Alongside the named solitaire modes, Rubah4d describes daily challenges with unique objectives and rewards. The description does not give examples of those objectives or explain how rewards are earned, so it does not establish a particular challenge format. These challenges are presented as an additional way to approach the card game beyond selecting one of its named variations.

Four named modes, with different documented details

The modes are not described with the same level of rule detail. Klondike has an ascending foundation goal, Spider has a descending-order and clear-all objective, FreeCell is defined by its face-up deal, and Patience is noted for its distinct rules without elaboration. This allows players to distinguish the options by the information provided without assuming that one mode uses another’s rules. The game description also presents classic card play as an option for a more relaxed session, alongside the challenges and variations.
