Sky Words Level 421 - Complete Answer Guide
Welcome to the complete answer guide for Sky Words Level 421, part of the Canada world (levels 401–480). This level presents you with 6 letter tiles — EFNORZ — and asks you to form all 7 valid words ranging from 3 to 6 letters. Every word on this page has been confirmed from live game data so you will never get a wrong answer here.
The key to beating Level 421 is placement order. Place FROZEN first — at 6 letters it is the longest word and reveals the most crossing tiles for the shorter entries. Once you have the longest word locked in, each crossing tile you reveal narrows down the remaining slots and the shorter words fall into place almost automatically. If you are completely stuck, scroll down to the Word-by-Word Breakdown — each entry gets its own vowel/consonant analysis so you can target the exact word that is blocking you.

3 Tips for Sky Words Level 421
Place FROZEN first — every time
Level 421 has 7 words and the longest is FROZEN at 6 letters. Drop it on the board first. Every crossing tile it reveals reduces the candidate list for shorter words dramatically — usually turning them into instant fills.
Every tile in EFNORZ is reusable
All 7 words are built from just 6 tiles — EFNORZ — and each letter can appear in as many words as needed. No single-use restrictions. If a word seems impossible, you are not missing tiles — check the crossing positions instead.
You are in the Canada world
Level 421 is part of the Canada world (levels 401–480). Difficulty climbs gradually within this world — nearby levels share similar letter patterns, so if you are stuck here, glancing at an adjacent level’s tile set often hints at what words are in scope.
How to Solve Sky Words Level 421
The three moves that clear a Sky Words board, applied to this one.
Read the tile set before you swipe
Level 421 gives you the tiles EFNORZ, and every answer is built from them — letters may be reused across words, but nothing outside the set can appear. Counting the tiles first rules out most of what comes to mind and is faster than guessing.
Place the longest word first
The longest answer runs to 6 letters and the shortest to 3. Placing the long one first consumes the awkward tiles and leaves the rest of the board far easier to read.
Use the world for context
Level 421 sits in Canada, world 7 of 30, covering levels 401–480. Difficulty climbs gradually inside a world, so a neighbouring level is the most useful hint when this one stalls.
