Daily Number Puzzle: Spot On

What is Spot On?

Spot On is a daily number puzzle made by the Revoba studio. It is free to play in the browser, with no download or sign-up. An Android version is also on Google Play. Languages: Turkish, English. It is currently an early build.

Spot On is a number puzzle: combine six numbers with addition, subtraction, multiplication and division to hit a three-digit target exactly. Four modes: three daily puzzles everyone shares (warm-up, medium, master), 300 levels across 10 seasons (some with a rule: at most 2 moves, use all six, or only + and −), unlimited practice and a two-player duel on one phone. Miss it and your closest number counts: exact is 3 stars, within 5 is 2, within 10 is 1. Every puzzle has a solution, shown after the round. Timer options, large text, hints and 18 badges. No sign-up, no ads, works offline.

How to play Spot On

Tap a number, pick an operation, tap a second number: the two merge into a new one. Each number is used once and you don't have to use them all. Hit the target and the round ends; otherwise press Submit and your closest number counts. In levels follow the rule shown on top; in a duel pass the phone between turns.

How are puzzles built and difficulty set in Spot On?

Every puzzle in Spot On is made of five digits and one big number. The digits run from 1 to 9, and no digit appears more than twice. The big number is 10, 20, 25, 50, 75 or 100. The daily target is picked between 101 and 999.

A solver sets the difficulty. It works out every result the six numbers can reach and how many different ways lead to each one. In the warm-up round the target is reachable with at most three numbers and at least four ways. The medium round needs at least four numbers. The master round needs at least five numbers and has no more than four ways to the target. The three rounds of a day never repeat the same set of digits.

Daily puzzles are numbered from puzzle 1 on 23 October 2026. Levels are grouped into 10 seasons of 30, running from Rehearsal to Champion. A new season opens once you clear level 30 of the season before. In the first two seasons the big number is only ever 10, 20, 50 or 100.

Who is Spot On for, and how do duels and badges work?

Spot On is for people who enjoy TV-style number rounds and want a daily number game of their own. If you know the Countdown numbers round, you already know the idea. Any child who can add, subtract, multiply and divide can play, and so can an adult who wants three puzzles a day. The Android version adds a daily reminder notification and haptic feedback.

In a duel two people take turns on one phone with the same numbers. An exact hit scores 10, within 5 scores 7 and within 10 scores 5. If the points are level, the shorter total time wins. The screen goes dark while the phone changes hands, so nobody sees the other player's moves. The timer applies to practice and levels; the daily puzzle is always untimed.

Some of the 18 badges take real skill. "Lightning" asks for an exact hit within 20 seconds. "No help needed" means solving the daily master round with no hint, and "Golden season" means 90 stars in one season. Streak badges come at 3, 7 and 30 days in a row. Your daily result is shared as text headed "Spot On #number".
