MEET CHESS CRUSADE It’s the game that’s easier than chess and harder than chess at the same time. It’s chess for the curious, and it’s a new challenge for the deck-builders. Wield powerful new character pieces like Nightrider, Archbishop, and Angel to attack or protect the king in stunningly colorful worlds. Checkmate is just the beginning. Even when one game ends, your strategy continues. Refine your deck, experiment with your opening line-up, plot your next character upgrade, redeem your rewards, and win your way to the nearly unstoppable Angel. The more you play, the more powerful you become. GAMEPLAY Gameplay starts with a few pieces; choose wisely or you won’t have long to live. With each turn you survive, earn more Material and spawn a strategic new piece from your battle complement. But watch out, the game can change in a single turn—who will your opponent spawn? If they’re saving their gold, you could get slapped with the Angel, and she’s anything but angelic. DECK-BUILDING Between games, build up your deck. Your deck has four card slots for Chess Crusade pieces—upgrade pawns to Rangers, sanctify your Archbishop, or run the brutal Rook Rush play. WARRIORS AND ROYALTY Chess Crusade springs from traditional chess—you’ll find the bishop, rook, knight, pawns and queen protecting the king. But in Chess Crusade, everyone in the kingdom has counterparts who are biggerbetterfaster. Ranger—Every pawn wishes he were a Ranger: the awesome hat, the damsels, and the freedom to move back and forth. Priest—The Priest sidles in the shadows, following in the bishop’s footsteps for a lower ante. Tower—He’s a rook in training. What he lacks in reach, he makes up for with his willing spirit. Princess—She’s delicate and beautiful, but she’ll send you straight to the gallows if you attack the throne. Nightrider—He’s in the king’s special forces, brave like a knight with sneak-attack range. Crusader—The Crusader is a battle machine. He’s all knight and all rook, balancing long-range straightlines with a hooked-L surprise. Archbishop—The Archbishop is holier and more corrupt, with a staggering 20-position reach. Angel—She’s terrifying. PACE Play ranked PvP games or casual PvE games at your speed; be a Sloth and sleep on your next play for 23 hours of the day, take the calculated approach in 15-minute rounds, or ratchet up the heat in turns once every minute. FRIENDS Crusade with friends or challenge foes from the global leaderboard. You can even spectate live games friends are playing or learn from the top players in the kingdom. WORLDS Earn beautiful new themes to frame your battles. From the lovely Queen’s Meadow to the fiery Lava Flows, you’re far away in an epic landscape plotting a sacrifice or the ultimate endgame. GEMS Customize your world with avatars, card pieces, and taunts (“Bean slouch!”) from the shoppe. WHAT THEY’RE SAYING: “It’s making me crazy. I cannot stop playing.” —JordyB “I’ve been playing chess for eight years and was skeptical a fun, new version could ever be created. I was wrong. It’s approachable, visually great, and addicting. I’ve played hundreds of games in just a few days.” - 04tuna “This game absolutely ruined me for regular chess. I can’t imagine playing now without Nightrider, Crusader, or Ranger.” - Rank13 “This game will resonate with people who already love chess but are open to new experiences.” - Whom’st

About

Undermine

Features
Read full description

Undermine is a tense two-player board game for one iPhone or iPad lying on the table between you. Take turns placing chips on your own entry row or moving any chip on the board — yours or your opponent's — one step in any direction. Be the first to line up four of your colour, across, down or diagonally. But 18 mines are hidden under the 6 × 6 board, three in every row, and nobody knows where. Whenever a chip steps on a mine, it flips to the other colour. Push your opponent's chip onto a mine and it becomes yours — or complete their line by accident and hand them the win. • Two players face to face on one device, or VS Bot at Easy, Normal and Hard • Tabletop layout: each player reads their own end of the screen • Learn in a minute with illustrated How to Play cards and in-game tips • Undo a move by watching a short ad • Your game is saved automatically — continue any time • View the mines when the game ends and see where it turned • Free with ads; a one-time Remove Ads purchase turns them off • English, Traditional Chinese and Korean
