A new kind of deckbuilding roguelike. In Lost Pages, you don't draw cards. You draw elements. Instead of drawing cards randomly, spells require elemental resources such as Fire, Water, Earth, and Air. Every turn, elements are drawn from the pool created by your deck, creating a completely new strategic system. This unique mechanic was recognized for its originality at the Google Indie Game Festival. Draw Elements, Not Cards Each spell requires elemental costs. Your deck determines the element pool, and every turn you draw elements randomly from that pool. Managing your elements and planning your turns becomes the core strategy. A new twist on the classic deckbuilding roguelike formula. Ether - A Unique Element A special element called Ether adds another layer of strategy. When drawn, Ether changes its nature instantly and always triggers an additional element draw, sometimes creating powerful chain reactions. Mastering Ether can completely change the flow of battle. Build Your Deck Discover and combine a wide variety of: - Magic Circles - Artifacts - Runes Every choice changes your strategy and opens new possibilities. Create powerful synergies and build your own unique deck. A 5-Act Roguelike Adventure Explore a roguelike map where every run is different. Face powerful elites, deadly bosses, and unpredictable encounters as you progress through the world. Challenge 100 Levels of Hazard Beyond the main adventure lies the Dimensional Gate. A special mode with 100 levels of escalating difficulty, designed for players seeking the ultimate challenge. How far can you go?

Jack the Ripper is hiding among us. Can you find him? In this turn-based detection game, two teams face off against each other: Jack the Ripper and the detectives. Jack has to get away with murder without being found out by the detectives, who in turn need to find out who he is. Unlike other detection games, you can't talk with the other players in Jack & Detectives, and you must figure out the truth based only on their actions. Players cannot get eliminated, so everyone gets to enjoy the game to its end. Furthermore, since a game only last ten minutes, you don't need to commit a lot of time just to play. ■ Jack: Commit murders without being found out. A serial killer lurking in the shadows. In order to win, he must make sure he isn't chosen during the voting phase. ■ Detectives: Find Jack, who is hidden among us. Private detectives hired by the London police. In order to win, they must correctly vote Jack out during the voting phase. ■ Jack maniac: Muddy the waters so that Jack isn't found. A maniac whose allegiance lies with Jack the Ripper. He wins if Jack wins, even if he gets voted out himself. The detectives must plan their moves to corner the suspect among them! At the start of each game, players are assigned a role at random. Then, everyone places their token on a London tile of their choosing. Jack must trick them and frame one of them! Once they have done so, night will fall, and Jack the Ripper will commit his first murder. (In certain cases, there will be no murder during the first night) Vote to choose whom to arrest! The detectives located near the crime scene will become suspects. Who's on justice's side? Who's the murderer among us? After the second murder, the voting phase starts. Everyone has to vote for the person that they think is secretly Jack the Ripper. This is where the real battle of wits between the detectives and Jack starts. ■ Cross-platform online play You can play online against console and mobile users. ■ Play against people from all over the world Win matches against worldwide challengers to earn rank points.

ReceptionRating · Positive reviews · Number of ratings

Lost Pages holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Lost Pages has 173 ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 50% of Lost Pages's written reviews are positive against 53% of Jack & Detectives's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 days. The most recent releases landed on September 29, 2026 and September 27, 2026 respectively.
