Playmobil
23. One may play with Playmobil, and it is not muktzah. However, one may not assemble or dismantle parts, e.g., parts that connect to create a person, as the attachment level is considered tight, and they usually remain assembled for a long time.
Rubik’s Cube
24. One may play with a Rubik’s cube on Shabbos. There is no issue of koseiv or tzoveia since one is just temporarily putting colors together. There is no issue of binyan b’keilim since everything is already attached; it just rotates around a single pin (שש''כ פט''ז אות כ''ה, חוט שני פל''ו הע' ה').
25. There is also no issue of borer, as all the pieces are connected. The player does not separate the desired from the undesired; he just sorts the colors within the “mixture” (מו''ר בעל שבט הקהתי, ספר עם מקדשי שביעי ח''ב פי''ד סכ''ו ).
Elastic Loom Bands
26. Loom Bands are sets of colored elastic bands with which one can make bracelets, necklaces, or the like. One may not play with them on Shabbos, as using them involves the melachos of kosheir, binyan b’keilim, and makeh b’patish, so they are also muktzah.
Cards
27. One may play with different cards on Shabbos, e.g., Quartets [Go Fish] or the like, especially when they have a chinuch purpose. The cards may be arranged a specific way to make the game play easier, as that is called immediate use [לאלתר]. However, they should not be arranged in a specific order after the game due to the issur of borer (שש''כ פט''ז אות ל''ה ).
Stickers
28. Decorative stickers are considered מוקצה מחמת איסור and may not be moved on Shabbos.
29. Gedolim pictures. Gedolim stickers or the like which are meant for children to play with and collect and eventually sometimes stick inside an album have the status of מלאכתם לאיסור ולהיתר and may be moved on Shabbos. They may also be played with on Shabbos (מ''ב סי' ש''ח סק''כ ). However, they may not be traded among friends in the manner of a business transaction due to the issur of business on Shabbos.
