Is Fiendish Sudoku Harder Than Expert Level?

From New York to Rome, Istanbul, Cairo, Iceland, and beyond, Adrian races against an invisible enemy that has protected the truth for over five hundred years. But as the final cipher draws closer, he realizes the greatest danger isn't unlocking the secret... it's surviving it.

Our entire class gets dragged into The Tyrant's Atonement game. The only way to escape alive is to reach a 100% atonement score. The system lets us choose our roles. The class belle, Isolde Adler, picks the tyrant's first love. Her atonement score shoots straight to 99% on the first day. The class president, Asher Brooks, chooses to be a loyal chancellor. His atonement score jumps to 80%. Spectators watching the game flood the screen with comments. "This new batch is smart and way better at picking roles than the last. They might just clear the game in three days." "Even if just one person hits 100%, the whole class goes free. I'm looking forward to seeing who finishes first." "My money's on the first love. She's already at 99%." Just as everyone starts celebrating, the next morning hits us with bad news. All 20 classmates who picked their roles are dead, and Isolde suffers the cruelest fate of all.

I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”

The day I was supposed to win the biggest award of my career, I walked in on my boyfriend, Ethan, in bed with another woman. He sneered, calling me a face-blind, scent-deaf bore in bed. I planned to expose his ass at the award ceremony. Instead, he and his lover mowed me down with their car. Next thing I knew, I woke up with them in an S-class horror survival game. Mortality rate: over 95%. We had to survive ten days in a haunted manor to be revived. Hit 100 on your Anxiety Level, and your soul is obliterated. Chloe, Ethan's lover, sneered. "Sensory defects? You can't recognize ghosts or smell danger. In a horror game, that’s a death sentence. You might as well just die." The others heard her and scrambled to team up. Me? I walked straight into the lair of the manor's final boss. The most powerful demon in the game wanted to devour my soul. I couldn't really see him. I just thought he was a cosplayer. I lunged forward, poked his abs, and pointed at the glowing crack in his chest. "Wow, you're really committed to the role. This getup must've cost a fortune."

I've chosen to participate in a death game. As long as I can escape from the murderer's killing spree in ten time loops, I'll be able to win at least 100 billion dollars. In the first loop, I have my apartment refurbished into a bank vault. Still, the killer is able to bust down my front door. In the second loop, I hide in the ceiling crawlspace. Yet, the killer is quick to locate me immediately, as though he knew where I was, to begin with. In the third loop, I finally realize that something's definitely fishy…

My father, Daniel Jacobson, teams up with the elders in my family to launch the Family app. Every child's behavior is converted into points, and those points determine who inherits the family's wealth. As the least favored daughter in the family, I am one of the first people forced to use it. "You earn one point for greeting your parents. Massaging shoulders or washing feet gives you ten points. Handing over your entire paycheck gets you 1,000 points. This is my original digital system for measuring good behavior." If I dare complain even once, or if I rank last on the scoreboard, Dad humiliates me relentlessly in the family group chat. He even forces me to kneel and wash the feet of whoever has the highest score as an apology. He looks at my hands that are red and scalded from the hot water and sighs. Then, his expression turns resolute again as he says, "I know it hurts now, but this is for your own good. A rough diamond has to be cut and polished before it can sparkle. I'm helping to smooth away your rough edges so your future will be smoother. "The points system is my greatest achievement. It's the deepest expression of a father's love." Today is Independence Day. It's also our family's annual scoreboard finalizing day. Dad invites all our relatives over. In front of everyone, he plans to announce that I, the child who ranks last, will be disowned. He wants everyone to see what happens to anyone who dares challenge his authority. "I'm doing this for the good of our family. Without rules, there can be no order. And without a strict upbringing, you won't build up the perfect character. One day, you'll understand my good intentions." But, Dad... I have already ended my own life by overdosing on some medicine. Right now, my lifeless body lies cold in the room upstairs, waiting for you to uncover it with your own hands.
