Higher or Lower
Will the next number be higher or lower? One wrong answer ends your streak. Extremes are safe. The middle is gambling.
A deceptively simple premise: will the next number be higher or lower than the last? Your streak is the only thing standing between you and bragging rights.
Higher-or-lower games sit in an interesting cognitive spot: there's genuinely no skill in any single guess (it's a coin flip dressed up with numbers), but the format has been used in behavioural research for decades precisely because of how compelling a growing streak feels, even when everyone involved knows intellectually it's pure chance. That's the same mechanism behind any 'just one more' loop — the closer you get to a personal best, the harder it is to stop. There's no trick to beating it, just the long-run math of probability and how long your nerve holds out before it does.
You're shown a value and asked whether the next one will be higher or lower. Guess correctly to extend your streak — one wrong guess ends the run.
Your score is your longest streak of consecutive correct guesses. There's no ceiling, just your nerve.
It's the gambling instinct in your brain, repurposed for something with zero financial downside.
Is it random or is there a pattern?
It's randomised within realistic ranges — no pattern to exploit, sorry.
What happens when I guess wrong?
Your streak resets to zero and you get to relive the disappointment immediately by starting again.
