Target Number

Five cards. One target. 75 seconds to nail the math.

What is Target Number?

Target Number is a Countdown-style arithmetic puzzle. You get five number cards and one target. Your job is to combine those cards with math operators and land on that number.

The game builds each puzzle by working backward from your five cards, so a target is chosen with an exact solution in mind. Most rounds have a clean answer waiting to be found. You just have to spot the path.

The core loop is simple. Read the target. Look at your cards. Build an expression with the operators. Watch the live result and distance update as you go, then submit when you think you have it. Get the distance to zero for a perfect hit.

How to Play

You build a math expression from the cards and operators on screen. Here is the flow:

1. Check the target goal shown at the top of the board.
2. Click a number card to drop that value into your expression. Each card can be used only once.
3. Click an operator: plus, minus, times, divide, or an open or close parenthesis for grouping.
4. Keep adding numbers and operators to build your formula. The result and distance update live as you build.
5. Use BACK to undo your last token, or CLEAR to wipe the expression and free up all your cards again.
6. Hit SUBMIT FORMULA when your result matches the target, or gets as close as you can.

Scoring & Rules

Each round runs on a 75-second countdown. The timer turns urgent and starts ticking in the final 10 seconds.

Your goal is the smallest possible distance between your result and the target. A distance of zero is an exact match and the best outcome. Your final result has to be a whole number that is zero or positive, matching Countdown rules. Anything that produces a negative or fractional total, or that has broken syntax, gets flagged as invalid and will not submit.

In a duel, an AI opponent solves alongside you. You win the round if your distance is less than or equal to the bot's. The round ends when you submit, when the bot locks its formula, or when the timer hits zero. Afterward you see the best solution the puzzle's solver found.

Strategy Tips

• Anchor on a big number. If you drew a 100, 75, 50, or 25, get close to the target with that large card first, then fine-tune.
• Multiply early, adjust late. Multiplication covers big distance fast. Use small cards with plus and minus to close the final gap.
• Watch the live distance label. It updates with every token, so you can see instantly whether a move helps or hurts.
• Use parentheses to control the order of operations. Grouping lets you build something like (75 minus 3) times 5 instead of fighting default precedence.
• Do not chase a perfect match if time is short. A close distance can still win the duel if it beats the bot.

Skills It Exercises

Target Number is designed to exercise mental arithmetic and number sense. You are constantly estimating, combining, and adjusting values against a clock, which keeps your working memory busy tracking which cards you have spent and how close your current result sits to the target.

It is a fun way to practice flexible calculation. There is rarely one path to a target, so you weigh options and switch approaches on the fly. With regular play you may get faster at spotting useful factor pairs and round-number shortcuts. Think of it as practice for the kind of quick math that comes up in everyday situations, packaged as a timed puzzle.
