Perimeter Zero vs Slidora

Perimeter Zero is a tower-defense game about running a private security operation, not casting spells. You're the commander: place cameras, lights, gates, guards, drones, and a growing arsenal of detection and response tools, then hold the perimeter as intruders test every gap in your coverage. See your coverage, not just your budget Every camera, sensor, and guard shows its real detection and response radius before the night starts. Placement isn't guesswork — you can see exactly where your perimeter is strong and where it's exposed, then build accordingly. A loop that tests you, not just your equipment When multiple threats hit at once, you choose which guard responds to which — a deliberate call under pressure, not an autopilot response. Detection, response, and slowdown layer together into real tactical decisions across cameras, lights, gates, K9 units, thermal towers, cyber nodes, and more. 22 contracts, from a starter warehouse to a national command network Start small with a two-door warehouse. Escalate through delivery depots, tech campuses, research labs, data vaults, airports, harbors, stadiums, hospitals, banks, and eventually a combined national command-network finale — each with its own threat mix, layout, and pressure. Nine intruder types, each demanding a different answer Prowlers, runners, saboteurs, hackers, insiders, credential thieves, vehicle crews, crew bosses, and stealth infiltrators all pressure your perimeter differently. Layer detection and response so nothing slips through unseen. Permanent progression that matters Spend contract earnings in the Upgrade Lab on sixteen permanent upgrades across four specializations — Perimeter Core, Command & Intel, Response Teams, and High-Security Ops. Every contract makes your operation stronger for the next one. Daily operations and mastery A rotating daily contract with its own modifier keeps every return trip different. Chase mastery stars, best grades, and win streaks across every site you've cleared. Fair monetization Banner ads appear only on menu screens — Home, Contracts, Upgrades, and Results. Active night gameplay is always ad-free. A single one-time Premium purchase removes ads entirely and adds no gameplay advantage; Restore Purchases is available anytime. Game Center support Leaderboards and achievements track contracts cleared, best cash hauls, daily streaks, and threats stopped — fully optional, and the game works completely fine if you're signed out. Build the perimeter. Watch the coverage. Hold the line.

A sliding photo puzzle you can win twice: once by finishing the picture, and once by finishing it in fewer slides than the solver that played the same scramble beside you. Slidora solves every board the moment it is dealt, so there is always a line to beat - and afterwards you replay both, move for move. Slidora is the classic 15-puzzle, remade calm. Pick a picture, pick a board from 3x3 to 6x6, and slide the tiles through the one empty space until the image comes back together. No timer, no lives, no score chasing you - just you, the picture and the quiet click of a tile finding its place. THE DUEL - YOUR ROUTE AGAINST THE SOLVER'S - The Coach solves your scramble as it is dealt, so its route runs beside yours from the first tile: tiles home, you against it, live under the board. - Finish, and the route review replays both boards side by side. Drag the slider and watch the two lines pull apart, slide by slide. - It names the exact move where you left the Coach's line, what the detour cost you, and the route efficiency you finished on. - Not in the mood to race? The same solver will show you the single smartest next slide, or glide the whole board home for you. TURN ANY PHOTO INTO A PUZZLE - Turn any photo from your gallery into a sliding puzzle in one tap - a face, a pet, a holiday, a place you miss. - Rebuilding a picture you love feels nothing like sorting numbers into rows. - Crop and frame the shot first, so the puzzle looks exactly the way you want it. - Slidora asks for photo access only the moment you tap Add a photo, and the picture never leaves your device. SIX BUILT-IN PICTURE PACKS - Transit Maps, Contour Maps, Skylines, Weaves, Circuit Boards and Farmlands - forty-eight pictures, all drawn for this game. - Each one carries long lines that cross the whole picture and colour that shifts corner to corner, so a tile tells you where it belongs. - Beat the Coach's route and you have out-planned the solver - every scramble is scored against it. - Two packs are open from the first launch; the rest unlock for good with one optional video each - no grind, no purchase. - Fresh art for the days you want a break from your own photos. BOARDS FROM 3x3 TO 6x6 - Start gentle on an eight-tile board or stretch out on a 35-tile challenge. - Big, readable tiles that stay clear even on the largest grid. - A number overlay you can switch on or off, and a peek at the full picture whenever you want the help. A DAILY PUZZLE FOR EVERYONE - One new picture every calendar day, the same board for every player in the world. - Come back tomorrow for a fresh slide and keep your streak alive. THE DUELS TAB - YOUR ROUTING, MEASURED - A bar for every unaided finish: the solver's route as a share of yours, green when you land within a tenth of its line. - The last dozen duels kept whole and replayable, move by move, whenever you want to see one again. - Your average route, your best one, and how many boards you have taken off the solver - as a ratio, never a bare count. - Badges for routing well and for turning up, never for raw speed. CALM BY DESIGN - No timer, no countdown, no lives, nothing shouting at you mid-slide. - Full light and dark mode, big readable tiles and large clear text throughout. - Every board saves itself the moment you leave and reopens exactly as it was. PERFECT FOR - Anyone who loves the classic 15-puzzle but is tired of plain numbered tiles. - Turning a favorite photo of family, pets or travel into a quiet little game. - Coffee breaks, waiting rooms and long journeys with no signal. - Winding down before sleep with something calm for your hands and your mind. PRIVATE AND OFFLINE - Works 100% offline. On a plane, in a basement, on a train through a tunnel - it plays the same. - No account, no login, no sign-up, no email address. Your photos stay on your device. - Free with ads, and Move Coach is always there for a hand when you want one. Pick a picture. Pick a board. Slide the last tile home.
