Protocol 4
Read full descriptionHide full description
Crack the code before your rival does. Protocol 4 is a hacker game of pure deduction. Every guess gives you signal readings; you break the passcode with logic, not luck. Play solo, take on the Daily Operation, or duel another operator in real time. REAL-TIME PvP DUELS Race: one passcode, two operators. First one through wins. Standoff: each of you sets the code the other must break. Two codes, one clock, and you watch them close in on yours. Outsmart your rival and claim the reward. DAILY OPERATION A new code every day, the same for everyone. Crack it, climb the daily leaderboard and earn double XP. BUILD YOUR EMPIRE Assemble mining rigs, expand your vault, and run overclocks. Your network keeps earning credits while you are away. SYNDICATES AND TERRITORY Join one of three syndicates, claim territory on the map, and take your share of the pot that every raid feeds. RAIDS Break into a rival operator's grid and take what they left unguarded, then set your own defenses before they come for you. GLOBAL LEADERBOARD Earn XP and climb fifteen ranks to become the ultimate Server King. MORE WAYS TO PLAY Quick Hacks for fast action, Training to sharpen your deduction, and 18 career contracts plus fresh daily missions. ARSENAL OF TOOLS Oracle Scan, Double XP and more hacking tools to gain the upper hand when a code will not give. Play in English, Turkish, Spanish, French, German or Portuguese, on iPhone and iPad. Are you ready to initiate Protocol 4?

SIMPLE TO LEARN, HARD TO MASTER Square Falls is a match-3 puzzle game that will keep you hooked for hours! Swap colorful squares to create matches, trigger massive chain reactions, and unlock powerful special candies that explode across the board. SPECIAL CANDIES & POWER-UPS - Striped Candies - match 4 in a line to clear an entire row or column with one move - Wrapped Candies - match in a T or L shape for a single massive explosion - Color Bombs - match 5 or more in a line to destroy every square of one color! GAME FEATURES - 45 hand-built levels across 3 themed worlds, then Endless Mode keeps generating fresh boards forever - Levels are not all the same task - score targets, collecting a candy color, popping blockers, clearing jelly and pulling off big combos, mixed in from early on - Board shapes beyond the classic square - bowls, diamonds, crosses, hourglasses and more, each with its own layout - Obstacles to work around: icing and chocolate blockers, licorice locks and cages, and jelly to clear - Strategic combo system with score multipliers, plus a Fever Mode for sustained cascades - Star rating system - earn up to 3 stars per level - Limited moves add strategic depth, with up to two free rescue offers if you run out - Shuffle power-up when you are stuck - or a free automatic reshuffle if the board itself runs dry - A winding world map - your progress as a journey, not a grid - Auto-save progress - pick up where you left off - Game Center leaderboards ranking how far you have come: highest level reached, plus total stars - No ads interrupting your gameplay - Play offline anytime, anywhere LIVES Square Falls uses a lives system: you start with 5 lives, and a spent life refills on its own after 30 minutes. A life is spent when an attempt ends without winning - losing a level, or choosing to abandon one already in progress (confirmed first, so it is never accidental) - never just for starting a level. Run out and you will see a countdown to the next free life. There is no way to pay past it: Square Falls has no In-App Purchases at all, and no ads. Waiting always works. CHALLENGE YOURSELF - Complete each level's own tasks before running out of moves - not always just a score - Plan ahead to create powerful combo chains - Each world introduces new board shapes and obstacles - Earn perfect 3-star ratings on every level - Compare your progress with friends on Game Center leaderboards HOW TO PLAY 1. Swipe a square toward an adjacent square to swap them - or tap one, then tap a neighbour 2. Create matches of 3 or more same-coloured squares 3. Trigger combos for bonus multipliers 4. Complete the level's tasks, shown before your first move, to win 5. Unlock special candies with matches of 4 or more LANGUAGE Square Falls is currently available in German only. Whether you are a casual puzzle fan or a match-3 master, Square Falls offers the perfect blend of strategy, skill and satisfying puzzle action!

Verdict
The clearest difference is in-app purchases: Square Falls at none against Protocol 4's 7. Square Falls also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 3 months). On price, device support and iOS requirement there is nothing between them.
