Sumdinger
The same idea in a compact form: six number cards, the four basic operations and a target to land on exactly, with three sums to solve each day instead of Numble's single target and bonus.
Numble is a Countdown-style daily maths game. Each day has a new target, 839 on November 4, 2026, and pressing Start reveals six numbers to work with, such as 2, 3, 7, 8, 50 and 75 in the game's own example. You combine them with the four basic operations, using brackets where needed, and pressing equals saves a result to reuse in the next expression. A bonus target and an archive add more. Hitting the number exactly is the thrill.
Every pick involves reaching a set number with arithmetic. The first group is the same six-numbers-and-four-operations puzzle with different counts of targets, timers and scoring. Then come ones that chain sums, roll dice or turn letters into numbers, and last are an equation guesser and two path puzzles that still end on an exact total.
The same idea in a compact form: six number cards, the four basic operations and a target to land on exactly, with three sums to solve each day instead of Numble's single target and bonus.
Six number tiles and the four operations aimed at a three-digit target, and when an exact hit is out of reach you still score by getting near it, a forgiving rule for hard days.
Five targets that climb in difficulty, each hit with the same six-number, four-operation toolkit and a single use of each number, so a full day is a longer workout than Numble's.
Seven rounds a day of the six-number problem, each target somewhere from 101 to 999, and a two-minute limit on every one, so speed counts alongside accuracy.
Another six-number target puzzle, this one built from small values, with a difficulty rating posted each day so you know what kind of solve to expect.
Pairs a numbers game with a letters game, three rounds apiece: reach targets with a six-number set, then form the longest possible word from nine letters, a mix that suits Numble players who also enjoy anagrams.
Builds toward the target in stages: no more than five steps, each tile spent once, and every intermediate result available for the next calculation, much as Numble lets you save a result and keep going.
Keeps the target fixed and changes the numbers: you roll dice and use arithmetic to turn whatever comes up into exactly 37, so the puzzle resets with every throw.
Turns words into numbers: A counts as 1, B as 2 and so on up to Z, so the words you form from eighteen tiles become values, which you then add, subtract and multiply toward an exact target.
Works backward from the target: deduce a hidden six-symbol equation that equals the posted number in six tries, and every attempt must itself evaluate to that number.
The exact-total idea set in a maze: plot a route from entrance to exit through numbered squares, keeping a running sum, so you finish on precisely the number you were given.
A one-minute arithmetic sprint: trace lines across adjacent tiles of a 5x5 number grid whose values add to the target, and longer lines and streaks earn more, a quick-fire version of reaching a set total.
Press Start to reveal the day's six numbers, then build expressions with brackets and the four operations to reach the target. Pressing equals saves a result so you can use it in a later expression, each step can be undone, and Reset clears everything if you want to begin again. A give-up button is there if the target proves out of reach.
Alongside the main target there is a bonus puzzle, and an archive holds earlier days. Players who want several targets at once can try SpotOn, with five targets of rising difficulty, Septonum, with seven timed rounds, or Sumdinger, which sets three sums every day.
You can undo steps, reset the board or give up and come back tomorrow. For partial credit, Tilehit scores you on how close you get when an exact hit is impossible, and Tot Up pairs its number rounds with a letters game for a change of pace.
