Sum Blocks

Drag blocks onto an 8x8 board. Fill a whole row or column and it blasts. Clear four lines and a math question appears under the board. Answer it and you are not given points — you are given a tool. A bomb that clears a 3x3 patch. A hammer that knocks a single block out. A shuffle that swaps the three pieces you are stuck with. Doing the math makes you stronger at the puzzle, and a child who never answers a question can still finish every level. SKILL MISSIONS Each mission is one arithmetic skill — times tables, sharing, big adding, taking away — and inside it every question is that one skill. Four levels each, with goals like "blast twelve lines" or "score 1,600 using thirty blocks or fewer". A block budget, not a clock, so nothing hurries a child. DAILY CHALLENGE One puzzle a day, built from the date itself, so every player in the world gets the same blocks in the same order. Play two days running and a streak starts. CLASSIC Endless blocks with no goal but your own best score. Easy, Normal and Hard change the shapes you are dealt, how fast the big ones arrive, and how long you get on a question. THE BLOCKS ARE NEVER TIMED A child can stare at a move for as long as they like. Only the bonus question has a countdown, and letting it run out costs nothing — it shows the answer and play carries on. NINETEEN KINDS OF QUESTION, KINDERGARTEN TO GRADE 6 Pick the grade and the questions stay inside it. Nothing above it can appear. Difficulty is a separate setting, so a grade 2 child can play Hard and a grade 6 child can play Easy. FOR PARENTS No accounts and no email. Scores stay on the device. There is one full-page ad after a game ends, never during play, and a single payment removes it for good. An adults' area behind a four-digit gate holds the purchase and an optional daily reminder.
