It is a defense game to protect the castle from enemy attack. If growth can be placed in the castle tower and the hero on each floor. Archer of the town is becoming a lot more more powerful the more upgrades. More than 80 heroes can use their own skills. Some heroes are made to give a strong archers of the town, another hero is cursed enemy. This strategy is important because only a hero can be mounted up to nine.

Orion Singularity is a trick-taking game at the edge of the event horizon: before every round you predict exactly how many tricks you will win — and only players who keep their word score full points. HOW IT WORKS Each round deals one more card. You read your hand and commit to a number. Hitting it exactly pays off; every trick too many or too few costs you. You must follow suit: if you hold the faction that was led, you have to play it. Trump beats the other factions — and the Singularity beats everything. FOUR FACTIONS Terran Alliance, Synth Collective, Xeno Swarm and Solaris Dominion: 60 richly illustrated, photoreal cards, each with its own character and story. The Codex lets you read up on every faction and every card. GAME MODES • Versus bots — three difficulty levels, fully offline, no account needed • Training — with hints and undo until the rules click • Local game — several people on one device; the hand is hidden at every handover • Online — invite friends with a join code, or quick match against others • Daily challenge — the same deal for everyone, with a daily leaderboard ALSO INSIDE • Game Center leaderboards and achievements • Statistics that follow you across your devices once you sign in • Runs on iPhone, iPad and Apple TV • Free, with no ads Bid.
