This type of logical puzzle was first seen in the Japan Puzzle Championship 2006 and is sometimes known as Doppelblock, or Smashed Sums. When played with pencil and paper, these puzzles can be hard work to solve. Sumaddle changes that by transforming the puzzles into interactive brain teasers that unfold before your eyes. Each puzzle has a unique solution. Finding the solution involves fitting the number combinations to the clues. The app makes it easy to view the possible combinations, you don’t need to do any sums in your head. Instead, you are able to focus on using logic to narrow down the combinations and find a fitting arrangement. The puzzles come in a range of sizes and difficulties, to suit all levels of skill and puzzling purposes. Choose a small puzzle to idle away a minute or two while waiting in a queue, or a big puzzle to give your brain some exercise during a coffee break!

An Klotski & Crossword influenced additive puzzle game . A grid. One rule you'll keep breaking, Vowels are your most valuable resource — and your greatest threat. Three or more identical vowels touching = they evaporate. You need them to make words. You can't hoard them. Tap a tile, swipe to slide it — tiles glide until they hit a wall or another tile. Line up letters to spell a word, tap to score it, and the board breathes back to life with freshly forged tiles. The catch: let three of the same vowel touch — anywhere, in any shape — and they vanish instantly. No score. No warning. Just gone. VEXED! is a pure word puzzle. No timers. No ads. No in-app purchases. Just you, the board, and the vowels you're desperately trying to keep apart. FEATURES · Four difficulties: Easy (5×5) through Hard (fills your screen) · Tile Forge system — score longer words to forge more tiles back · Vowel danger radar — the board pulses when a cluster is forming · Combo multiplier — chain words without losing vowels · Word history strip — tap any scored word for its definition · Arcade Mode — vivid background, textured tiles, bold scoreboard · Peak Vexation — per-difficulty high score on the start screen Can you reach an S grade?

Verdict
The clearest difference is in-app purchases: VEXED! at none against Sumaddle's 15. VEXED! also leads on update cadence (every 4 days vs every 3 weeks). Sumaddle's advantage is ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.
