How to build LINUX from the tiles
In 7 Little Words you don't type the answer — you assemble it from the puzzle's shared tile bank, and every tile is used exactly once across all seven answers. Puzzle 5's tiles for September 25, 2026 are:
AR · RES · TING · LI · NUX · AG · LA · RE · REST · RIN · GING · LAN · ZAR · OTE · TRAN · SA · LPI · NE · ABSE · ILS
LINUX is built by combining the tiles LI · NUX in order. Because those tiles come out of the shared bank, locking in LINUX early also narrows what's left for the other six clues.
