About Spell Check
Spell Check puts the most commonly misspelled words in English in front of you, two at a time. One version is right. The other is the mistake that people actually make. Choose.
How it works
Each question is a pair of buttons. Tap the correct spelling. The right one turns green either way, so you see the answer even when you miss. A round is ten words, drawn from a list of about sixty.
The wrong versions are not invented at random. They are the usual errors: a doubled letter left single, an "ie" turned to "ei", a silent letter dropped. That is what makes the game harder than it sounds. Both versions look familiar because you have seen both.
Spellings follow British usage, so you will meet "neighbour" with a U.
Rules worth knowing
Doubles cause the most trouble. "Accommodate" has two Cs and two Ms. "Necessary" has one C and two Ss. "Embarrass" has two Rs and two Ss. "Recommend" has one C and two Ms. "Occurred" doubles both the C and the R.
I before E, except after C, works for "believe", "achieve", "piece" and "receive". It fails for "weird" and "foreign", which simply have to be learned.
Listen for the hidden sounds. "February" has an R after the B. "Wednesday" has a D before the N. "Library" has two Rs. "Government" has an N before the M.
Drop the E, or not. "Truly" and "argument" lose the E of "true" and "argue". "Sincerely" and "definitely" keep theirs.
"Separate" has "a rat" in the middle. "Definitely" contains "finite". Small tricks like these stick.
"Forty" has no U, though "four" does.
Play a few rounds and the same words will come round again, which is how spelling is learned. Few HTML5 games are as directly useful.
