Strategy Tips for MONO Plays

Play MONO as a setup: MONO itself is valid (6pts). Play it early and extend into MONOPOLY, MONOTONE, or MONOLITH on your next turn. This two-turn strategy lets you score twice from the same prefix.

Double-O advantage: MONO has two O's. With 8 O-tiles in the bag, drawing M-O-N-O is more likely than you'd think. When you see two O's with M and N, immediately think MONO bingo.

Common completions: The 3-letter endings that create 7-letter MONO words: -RCH (MONARCH), -LOG (MONOLOG), -CLE (MONOCLE). For 8-letter words: -POLY, -LITH, -TONE, -GRAM, -RAIL.

💡 Key Insight

MONO uses M (3pts) plus three 1-point tiles, totalling 6 base points. This is higher than TRI (3pts) or BI (4pts) — meaning your MONO bingos start with a scoring advantage before adding completion tiles. A MONO bingo with common letters scores 56+ points minimum.

MONO vs POLY: Prefix Comparison

MONO (one) and POLY (many) are opposites — and both are powerful Scrabble prefixes:

MONO (6pts base)

4 tiles, common letters (M+O+N+O). Familiar words: MONOPOLY, MONOLITH, MONOTONE. Higher base score thanks to M=3.

POLY (9pts base)

4 tiles, includes Y (P=3, O=1, L=1, Y=4). Fewer total words but higher base score. POLYGON, POLYMER, POLYMATH.
