Play Higher or Lower Online Free — Solo or With Friends

How to Play

1. Pick a game type. Number Ladder is a guessing streak. Which is bigger? is a one-minute mental maths sprint.
2. Choose Easy, Medium or Hard, then press Start. A three-two-one countdown begins the run.
3. In Number Ladder, a number from 1 to 100 appears. Tap Higher ▲ if you think the next number will be bigger, or Lower ▼ if you think it will be smaller.
4. A right guess turns the new number into your current number and adds one to your streak. Keep going until you guess wrong.
5. In Which is bigger?, two sums sit side by side, such as 17 + 28 and 52 − 9. Tap the one with the bigger answer, then the next pair appears at once.

On a computer, use the up and down arrow keys (or H and L) for Number Ladder, and the left and right arrow keys for Which is bigger?.

Rules

In Number Ladder, the next number is never the same as the current one, so every guess is either right or wrong. Your score is the length of your streak, and the first wrong guess ends the run after the real number is shown. A run also stops after three minutes.

In Which is bigger?, you have 60 seconds. Each right tap earns a point, and each wrong tap takes one away, but your score never drops below zero. After a wrong tap the cards lock for a short moment, so tapping wildly does not help. The two answers are never equal, and every answer is a whole number.

The level changes the game itself. On Easy, Number Ladder shows a hint line and rarely lands in the tricky middle, while Hard often picks a next number close to the current one. For sums, Easy uses adding and taking away up to 20, Medium adds times tables up to 10 and numbers up to 100, and Hard mixes bigger multiplication, division and answers that sit very close together.

Tips & Strategy

• Think about how many numbers are left on each side. If the number is 80, only 20 numbers are above it and 79 are below, so Lower is the smarter guess. The Easy hint line shows this count for you.
• Slow down near the middle. A number between 45 and 55 is close to a 50-50 call. Take a breath and pick a side calmly.
• Round first, then check. For 52 − 9, think "about 43"; for 17 + 28, think "about 45". If the rough answers are far apart, tap straight away.
• Use the last digit when answers are close. On Hard, two sums may differ by just one or two. Work out the units digit of each answer to settle it.
• Turn division into times tables. 84 ÷ 7 is simply "what times 7 makes 84?" Knowing your tables to 12 makes Hard far easier.

Game Modes

Solo is a personal challenge. Your best score is saved separately for each game type and each level, so a long Easy streak never hides your Hard record. Two players on one phone share a split screen, with the top half turned round so you can sit facing each other. Both of you get exactly the same numbers or sums, which makes the duel completely fair. With three to eight players, everyone takes a turn on the same phone in order, and a scoreboard fills in as each person finishes.

Play with Friends Online

Choose Play Online, create a room and send the link or code to your group. Up to eight people can join. When the host presses Start, every phone counts down together and everyone plays the same numbers or sums at the same moment. Live scores show how your friends are doing while you play. If someone's connection drops, the host's phone ends the race once the time is up, so the rest of the room is never left waiting.
