The basic gameplay and goal of Phase 10: World Tour remain consistent regardless of the playing mode players choose. During each phase of the game, players are required to collect a set of cards and once they have all of them on hand, they can throw those cards towards the competitors (computer bots or real online players) and move on to the next phase. Whoever completes the 10 phases first wins the game. Meanwhile, the game settings change from time to time as if players are travelling from place to place around the world. After starting the game, players can decide whether they want to participate the game in offline mode—the journey, or online multiplayer mode. When entering the journey mode, players will see their gaming interface as a winding river with locked rocks. Their goal is to unlocks the tasks on each rock and move it towards the end of the river to complete the current phase. In order to reach each goal, players need to use something called “green lightning bolts” which are displayed and automatically recharging on the top area of the screen. While players moving along and unlocking the new tasks, they can also view their opponents’ game progress on their interface.  Players can also view the cards at hand and their on-going tasks; then they take turns to tap and pick up cards to complete the task. At the end, players need to eliminate the remaining cards still on hand because those cards are minus points for the next phase. If players choose to participate in online multiplayer games, the core principle and gameplay remain the same. The only difference is that players must spend coins to join online competitions and the coins are their bets, which they either win or lose in this gaming mode. Coins can be obtained via task completion rewards and ads-walls. Plus, as the difficulty level moves up, players can also resort to in-game boosters, which are displayed at each phase or can be further purchased through in-game spending.
