Strategy: Playing Long MICRO Words

MICRO words excel in two situations: bingo plays from your rack and extensions of existing words on the board.

Bingo from rack: If you hold M-I-C-R-O plus two more tiles, check for valid 7-letter MICRO words. MICROBE needs just B+E with MICRO. MICRONS needs N+S. The 50-point bonus makes these plays game-changing.

Extend existing words: If MICRO is already on the board, add letters to make MICROS, MICROBE, MICRON. You score the full extended word without needing to replay the existing tiles.

Play MICRO first, extend later: Drop MICRO (9pts) on your turn, then on the next turn extend to MICROBE or MICRON when you draw the right tiles. This two-turn strategy is reliable because MICRO has many valid extensions.

💡 Key Insight

MICRO uses only common tiles (M=3, I=1, C=3, R=1, O=1 — all worth 1-3 points each). This means you'll draw these tiles frequently. The challenge isn't finding the tiles — it's finding board space for 5+ letter words.
