Challenge yourself by outsmarting opponents of various skill levels to strengthen yours. If you prefer to play solo, level up your abilities against the computer, choosing from a range of difficulty settings—from beginner to World Champion. Whether you're just learning the game or aiming for grandmaster status, interactive hints help refine your moves to get you there.How to Play Chess FreeChess Free follows the classic rules of chess. The objective is to checkmate your opponent's king, meaning it is in a position to be captured and cannot escape.You can play against the computer, compete online with real players, or share the same screen with a friend. With 18 difficulty levels ranging from Beginner to World Champion, you can play based on your level.Depending on your level, you can choose a "handicap," so you have a bit of an advantage. You can also enable hints and interactive tips to help guide you throughout.The rules are basic—players take turns moving their pieces. Pawns move forward but capture diagonally, knights move in an L-shape, and other pieces have unique movement patterns. Strategy is key in chess. Protect your pieces, control the center of the board, and anticipate your opponent's moves. The game ends when one player's king is checkmated, resulting in a win or if a draw occurs under certain conditions.In chess, a draw is a result where neither player wins, and the game ends in a tie. This can happen for several reasons, such as stalemate (where a player has no legal moves but is not in check), repetition of the same position three times, 50 moves without a capture or pawn move, insufficient material to checkmate, or mutual agreement between the players.Made a mistake? No problem—use the move cancel feature to undo and rethink your strategy. After each match, detailed analysis highlights errors and suggests better moves, while the option to replay specific moments helps reinforce learning.You can save your rating and pick different time control modes like bullet, blitz, and rapid. Customize the board and pieces to your liking, review your move history, and even express yourself with playful cartoon emotions as you interact with your opponent.Special Chess Moves to KnowCastlingCastling is a special chess move involving the king and a rook. It’s only allowed if neither the king nor the rook have moved previously, and there are no pieces between them. Additionally, the king cannot be in check, and it must not move through or land on any square that is under attack. This move helps protect the king and connect the rooks for better defense.Taking the passTaking the pass, or en passant, is a special pawn capture in chess. If your opponent moves a pawn two squares forward and lands next to your pawn, you can capture it on your next move as if it had only moved one square. Your pawn will take its place, but this capture must be done immediately.More Games Like ThisIf you are a board game fiend, we have you covered!

Arkadium's Bubble Shooter is an exciting casual bubble shooter game. Match three or more bubbles of the same color to clear them and increase your score. Let's get popping!Building up on the success of Taito’s Puzzle Bobble, which became known in the Western world as Bust a Move, Arkadium’s Bubble Shooter represents an exciting twist in this peculiar genre. This version differs from those that inspired it mainly because there are no time constraints: you can carefully plan your move using all the time in this world, because your only limit is the number of moves you avail of.How to Play Arkadium's Bubble ShooterThe objective of the game is to shoot your way through the levels by matching three or more bubbles with the same color. Think carefully about where you shoot and consider what color is coming next by looking below the bubble loaded. If this secondary bubble works better, you can switch to it.Choose your moves wiselyThe challenge is to complete each level within the moves limit. The fewer moves it takes you to complete a level, the more moves you get for the next stage. If you use all your moves, the game ends, and you're back at level 1 to try again!Tackle each unique levelEvery level in Arkadium's Bubble Shooter has a unique design and layout. There are conventional bubbles, but also rocks, ice balls, bombs, and other bubble types to help or hinder your progress. These unique bubbles, combined with the moves limit, add an element of problem-solving to the game.Additional novelties brought by this version of the bubble shooting classic are obstacle bubbles:Stone Bubbles cannot be popped but can only be cleared by removing the bubbles they are attached to. Ice Bubbles are frozen ones and need to be thawed before they can be popped. Once you thaw them, their color is revealed, and you can treat them as ordinary bubbles.Arkadium’s version introduces a few power-ups you can use too:Lighting bubbles, once cleared, will get rid of the whole row they are placed ontoBomb bubbles will explode when impacted, clearing a circular area around themRainbow bubbles are wild cards; they can match any color that touches themMore Games Like ThisCheck out the classic Bubble Shooter for another free online bubble shooting game!
