Protocol 4 vs Killer Sudoku

Crack the code before your rival does. Protocol 4 is a hacker game of pure deduction. Every guess gives you signal readings; you break the passcode with logic, not luck. Play solo, take on the Daily Operation, or duel another operator in real time. REAL-TIME PvP DUELS Race: one passcode, two operators. First one through wins. Standoff: each of you sets the code the other must break. Two codes, one clock, and you watch them close in on yours. Outsmart your rival and claim the reward. DAILY OPERATION A new code every day, the same for everyone. Crack it, climb the daily leaderboard and earn double XP. BUILD YOUR EMPIRE Assemble mining rigs, expand your vault, and run overclocks. Your network keeps earning credits while you are away. SYNDICATES AND TERRITORY Join one of three syndicates, claim territory on the map, and take your share of the pot that every raid feeds. RAIDS Break into a rival operator's grid and take what they left unguarded, then set your own defenses before they come for you. GLOBAL LEADERBOARD Earn XP and climb fifteen ranks to become the ultimate Server King. MORE WAYS TO PLAY Quick Hacks for fast action, Training to sharpen your deduction, and 18 career contracts plus fresh daily missions.

Killer Sudoku for people who hate ad-bloated puzzle apps. Bento is a hand-curated Killer Sudoku game for iPhone and iPad. No ads. No subscription. No login. No tracking. Just puzzles, made for the bedside table. WHAT'S KILLER SUDOKU? It's the Sudoku you know - fill the 9×9 grid so every row, column, and 3×3 box has the digits 1–9 - with a twist: the grid is divided into colored "cages", and the digits inside each cage must add up to the cage's number (with no repeats). It plays like Sudoku crossed with a math puzzle, and once you've tried it, regular Sudoku starts to feel one-dimensional. REGULAR SUDOKU The classic game, no cages. Rows, columns and boxes, nothing else to keep in your head - the one you already know how to play, built with the same care as the rest of Bento. 100 HAND-CURATED PUZZLES Every puzzle in Bento is generated and verified for a unique solution - no broken puzzles, no guesswork required. 20 Easy / 25 Medium / 25 Hard / 30 Expert across the adult catalogue. Plus a fresh daily puzzle every day, free forever. KIDS MODE A separate catalogue of 48 puzzles on smaller 4×4 and 6×6 grids - perfect for teaching the cage-summing mechanic to a young learner. Brighter colors, more forgiving scoring, more hints. Toggle on the home screen. ONE-TIME UNLOCK Bento Pro is a single in-app purchase - no recurring charges. You get every puzzle in adult and kids modes, every difficulty. Try the first 3 puzzles of every difficulty plus the daily puzzle for free, indefinitely. No coercive trial periods, no manipulative free-but-not-really tier. DESIGNED FOR FOCUS • Neobrutalist sticker UI - bold colors, satisfying tactile feel • Classical-grid mode for purists who want plain white cells • Strict mode (3-mistake game over) for players who want the tension • Per-puzzle stars track your cleanest solves separately from your fastest • Full undo history, smart hints, pencil notes • Replay any solved puzzle; share your trophy card as a PNG • Daily streak counter PRIVACY-FIRST Bento collects nothing.

WHO IT'S FOR • Sudoku players bored of vanilla 9×9 and looking for the next twist • Parents who want to teach their 6-year-old logic puzzles without screens of ads • Anyone who's deleted a "free" Sudoku app after the third 30-second ad in five minutes Privacy Policy: https://sararu.net/bento/privacy-policy.html Terms of Use: https://sararu.net/bento/terms-of-use.html
