Get a better view of the school sim with this dedicated high-resolution version for tablets! The prison from Hard Time has closed down and re-opened as a school, but the challenge to survive and thrive remains the same. Live every hour of every day in real-time - from getting out of bed in the morning to attending a timetable full of classes, as you explore a city filled with interactive props. Picking up knowledge from each class helps you answer real questions in 10 different subjects, as you work towards the grades you need to graduate. But with over 100 fellow students walking the halls, an equally important popularity contest decides whether your days are filled with fun or fear. Although the game is mostly free to play, you can upgrade to a "Private" education to remove ads and make the school your own - starting with a student of your own creation and saving your changes to all 10 classes as well as the teachers and civilians. Private students also benefit from a more continuous experience that never ends until you want it to. BASIC CONTROLS: In-game tutorials explain in more depth, but the basic controls are as follows: A = Attack (on its own to kick, with a direction to punch) G = Grapple / Throw R = Run P = Pick-Up / Drop (with a direction to prioritize objects, without to prioritize furniture) T = Taunt (interact with props) OTHER CONTROLS - Press ATTACK and RUN together to launch a powerful attack. - Press any button with any direction (or none) in a grapple to trigger different moves. - Press RUN and PICK-UP together to set fire to a small object (which can then be used to set fire to a large object). - Touch the clock or health meter to pause the game for more options. - Tap the speech bubbles to speed through conversations. PERFORMANCE - If you find your device struggles to display lots of characters, considering keeping the "Population" option low. - "Speed Up Frame Rate" sleeping will require good performance, so consider leaving it on "Speed Up Clock". - Head to the "Display" options to tone down other features.

Burn it down! • Gravity - Took it all from freezing time... Well, play with low / high gravity or just turn it off like you are in space ;) • Control of gameplay - Too many debris on the screen and the game lags?

Verdict

The call

The clearest difference is ads: School Days HD at none against Ultimate Destruction Simulator's shown. School Days HD also leads on iOS requirement (10.0 vs 14.0). Ultimate Destruction Simulator's advantage is update cadence (every 2 weeks vs every 3 months) and device support (3 vs 1). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. School Days HD sells 1 one-off in-app purchase and Ultimate Destruction Simulator sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Ultimate Destruction Simulator holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 369 and 244 respectively.
