Many players mistakenly believe they can only add tiles to existing sets, but the rules actually allow for significant manipulation of the board.
Yes, according to the Rummikub Official Rulebook, you can move, rearrange, and even dismantle existing combinations on the table during your turn.

Official Rule Breakdown
According to the Rummikub Official Rulebook, manipulation is a key strategic element. During a turn, a player may move tiles, dismantle existing combinations, or rearrange them to facilitate playing tiles from their rack. This includes splitting a long run into two smaller runs, adding tiles to the ends of a run to remove a tile from the other end, or taking a single tile from a group of four to use elsewhere. Crucially, at the end of the turn, all tiles on the table must be part of valid run…
Step-by-Step
- Step 1: Identify existing combinations on the table that can be modified.
- Step 2: Dismantle or rearrange these combinations using tiles from your rack or by moving existing table tiles.
- Step 3: Ensure all tiles moved or rearranged form new valid runs or groups.
- Step 4: Verify that no tiles are left 'orphaned' or invalid at the conclusion of the turn.
Example Play Situation
Alice has a Blue 6 on her rack. She sees a Blue 4-5-7-8 run on the table. Alice moves the Blue 5 to a different set, uses her Blue 6 to complete the 4-5-6-7-8 run, and then uses the now-free Blue 5 to help form a new combination.

Common Misconceptions
- Thinking you can only add tiles to the ends of a run
- Believing you can leave a single tile alone on the table
- Assuming you can only manipulate your own tiles
