Einstein Sudoku is a logic puzzle game similar to Sudoku but using picture icons instead of numbers. The puzzles ask the player to solve "who lives in what house, eats what food, drinks what drink, etc" based on visual clues or facts given about the puzzle. There are an unlimited number of puzzles with different sizes (4x4, 5x5, 6x6), 2 levels of difficulty as well as a challenge mode for each that asks a simple question like "Who drinks the water?". Each puzzle started by the player has a unique solution with a set of clues given to help the player solve the puzzle. Clues can be queried by players to explain the meaning of each. Players can also "take a clue" which allows them to make progress with the puzzle, but with a time penalty added to the score. ## Key features - Picture icon logic puzzles - Unlimited puzzles - Multiple puzzle sizes (4x4, 5x5, 6x6) - Two difficulty levels - Challenge mode - Clue explanation and hints ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | 10 Puzzle Tickets | $0.99 | one-time | | 25 Puzzle Tickets | $1.99 | one-time | | 75 Puzzle Tickets | $3.99 | one-time | ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/einstein-sudoku/id1579067860/reviews.md ### 1/5 — Buggy *2025-03-16, version 1.5.6* Showing zero tickets so can’t start a game. ### 1/5 — Rip Of, paid for 75 tickets got about 10 *2025-01-22, version 1.5.6* And doesn’t even give you the 1 free game a day it advertises. I bought the most tickets - 75 - and got 2 short play sessions totaling 10 games. Total rip off. ### 1/5 — GAME BROKEN *2025-01-05, version 1.5.6* The game has stopped working: cannot eliminate items! ### 1/5 — Game is BROKEN *2025-01-04* The game no longer works. You can’t click on an item to delete it! ### 3/5 — App has turned majorly buggy, making it useless *2023-03-20, version 1.5.6* I used to absolutely love this app but lately the game will not allow you to make a selection (for example, to eliminate one of the choices or to select one of all). When I press into the cell it completely disappears (Goes blank). Of course it causes you to lose the ticket too. Stopped playing for a while hoping it was just a glitch (and forgot about why I wasn’t playing), but just went to play one and it’s happening again. I don’t have Facebook so I can’t check or post on the support page. Hopefully the developer will reach out? Thanks in advance. ### 4/5 — One of my favs *2022-10-02, version 1.5.6* So glad I found this. I still have its predecessor Virtual Suduko 2, which I love love love, but hasn’t been upgraded in forever. Many things are the same with little tweaks like new icons and a refreshed game board. The clues are slightly different as well so my time is a little slower while I learn the new layout, and I wish there was a pause button. The only thing preventing a 5 star review is the need for tickets. However, watching many similar games disappear I’m willing to pay (so far) reasonable fees to get tickets. I’m desperately hoping there are others out there who love this game as much as I do who will be willing to support the game by buying tickets. I’m also hoping the developers love the game and keep it updated and current. I’ll be sad when VisualSudoku2 finally dies, so here’s to a long life to Einstein Sudoku! ### 5/5 — Great game *2022-01-04, version 1.5.5* I love the new variations of this game. Sometimes I like to work on the challenge and earn tickets, sometimes I like to just play the ninja level 6. Working on the challenge to earn tickets is a logic and memory workout. ### 5/5 — Awesome game *2021-11-17, version 1.4.1* So glad picture sudoku is back. Absolutely love this game. Only suggestion is to provide an option to keep clues in place. I love the greying out when they are complete but the rearranging is irritating. ### 5/5 — Great game! *2021-11-16, version 1.4.1* I love these type games. I only wish this game had a pause button. ### 5/5 — Super fun! *2021-11-13, version 1.4.1* Takes a minute to get used to it but then you don’t want to stop playing 😊👍👍👍 ## Frequently asked questions about Einstein Sudoku ### What is Einstein Sudoku?
