Different return value Truffle & online compiler

Question

Using the online solidity compiler startGame() returns false, but using truffle this function returns a long hex string: 0xf697bd4ff4f5574f3cf73cd46a18087a5a0cf1aa1580fd4992ab20f574a808fe

function startGame() critical returns (bool) {
    Player player = players[msg.sender];
    if (player.ready) { 
        if (player.balance < minimumwager) { throw; }
            waiting.push(player);
            numWaiting++;
            if (numWaiting > 1) { 
                var thismatchup =  makeMatchup();
                player.playing = true;
                matchupMade(thismatchup); 
                return true; 
            }
            else {
                player.playing = true;
                playerWaiting(player.ethaddress);
                return false; 
            }
        }
    }
}

Answer 1

Invoking startGame with .call() in Truffle solved the issue: startGame.call()
