Higher or lower, one number at a time

Enter a number of your choice. + means the secret is higher; − means it is lower. No number is prefilled and no calculated range is shown. The first correct guess wins.

Three bot strategies

Easy guesses randomly among the remaining numbers. Medium favours the middle area. Hard halves the search range each turn. Records and real community comparisons use the same difficulty and rules.
