Beginner or advanced, become a chess master, without ever being disturbed by ads. Do you want to master the most prestigious, the classiest game ever, while having fun? It's EASY! For starters, there are no ads to distract you. There's no account to create, and you don't even need to be connected to the Internet. So, how does it work? If you are a beginner, let yourself be guided by the introductory lessons included. The lessons are SHORT and EASY. Right from the start, you begin playing by moving pieces, and you learn the rules of the game while having fun. The first 40 lessons are free. Once you know the rules, you start playing real games! The coach shows you the moves a Grandmaster would pick. Not just one move, but THE 4 BEST MOVES. Sounds too simple? But think about it... How did you learn to speak as a child? Did you take grammar and spelling lessons? Of course not. You listened to the adults talk and then you went for it! Because that's how you learn! This app allows you to do just that, AND IT WORKS! From the very first games, you start learning effortlessly. You immediately enjoy playing, and after a while you notice that the right moves come to mind naturally, as if they were obvious. Gradually, you deactivate the suggestions and play by yourself. At the end of each game, the coach shows you the good and bad moves you've made. You can better understand what happened, and you can even try out other moves to improve. If this sounds unbelievable, you should read the user reviews for our app. It has one of the highest satisfaction ratings on the App Store, in all countries. FOR BEGINNERS, THIS APP... • contains introductory chess lessons that are suitable even for children. The first 40 are free. • shows you all the possible moves of a piece when you touch it. • explains why certain moves are forbidden. • can suggest 4 to 6 excellent moves at any one time.

Read full description

Orbital Defense Protocol is a fast, focused, portrait-mode tower defense for iPhone and iPad. Place turrets, set traps, call orbital strikes, and hold the line through 10 sections of escalating hostile waves. CORE LOOP • Drag turrets onto the grid during prep. Tap to upgrade, sell, or specialise. • 6 archetypes: Pulse, Railgun, Frost, Blast, Gatling, and Command. Each upgrades in three channels (Damage / Range / Rate) and forks into a permanent specialisation at tier 6. • 5 trap and ability cards: Spike Strip, Slow Goo, Knockback Plate, Orbital Strike, and Stasis Field. Drag to deploy. • Tap MONSTERS to see the next wave's hostile profile — HP, speed, armor, shield resist — and pick the right damage type. DESTRUCTIBLE BATTLEFIELD • Walling off the path is legal. Hostiles will pound your turrets to rubble — every tower has hull HP, every enemy has melee DPS. • Rocks blocking your line of fire? Tap them. Spend $50, clear the tile, reroute the enemy path. • 7 hostile archetypes: BASIC, FAST, TANK, FLIER, SHIELDED, HEALER, BOSS. Each has its own counter. CAMPAIGN • 10 sections × 20 waves = 200 levels. • 5 difficulties from Easy to Extreme — adjustable per run. • Persistent top-scores leaderboard tracks your best clears and wipes. NO FRICTION • No ads. • No in-app purchases. • No network required — plays anywhere. • No data collected, no analytics, no tracking. Built for one-handed portrait play. Boots in seconds, drops you straight into the build phase. Set a difficulty, tap ENGAGE HOSTILES, and defend.
