SumSquare
A little number puzzle for every day.
A friendly, family-oriented math-grid puzzler for a quick Daily challenge or an unhurried Practice session. Pip is there to help while every row and column works toward its target.
Both directions have to land at once.
Every row and column shows an operation and a target answer.
Apply the operation in order.
Left to right along a row, top to bottom down a column. Place numbers so both directions reach their targets at the same time, which is the whole puzzle: a number that fixes a row can break the column running through it.
Six operations are in play. Add, subtract, multiply, divide, average, and square. The gentler grids stay with add and subtract; averages and squares arrive as the grids grow.
Make today count, or play at your own pace.
Two modes, and they want different things from you.
Daily Mode keeps a streak.
Choose from Very Easy, Easy, Medium, or Hard and solve that day's puzzle against the clock. The included library has 30 Daily puzzles per difficulty. Turn on a local reminder if you want the nudge, or leave it off.
Practice Mode does not.
Unlimited hints and no point drain. Take as long as you like, on any difficulty, without a clock deciding how the run went.
120 included Daily puzzles, with room to keep going.
120 included Daily puzzles
That is 30 each in Very Easy, Easy, Medium, and Hard. Gentler grids begin with add and subtract; later difficulties bring in multiply, divide, average, and square.
Four optional 60-day packs
Each pack adds 60 Daily days per difficulty, or 240 puzzles across all four difficulties. Packs are separate purchases, so you choose how far to extend the library.
Daily Club keeps the Daily going
Daily Club includes every puzzle pack while active and continues with fresh Daily puzzles after the owned library is exhausted.
