Cartilo: A Relaxing Card Sort Puzzle

Cartilo is a calm card sorting game where you organize families of cards by color and symbol. Tap to move cards and clear the board at your own pace.

Cartilo is a card sort puzzle designed for players who enjoy a quiet, thoughtful challenge. You can play this card sort game online free in your browser, offering a clean interface where the focus remains entirely on the logic of the cards. The game presents you with several piles of cards that are shuffled together. Your objective is to rearrange them until every pile contains only cards of the same family, creating a sense of order from the initial shuffle.

In this stack sort color puzzle, you will find a variety of families, each distinguished by a specific color and a unique symbol. This dual identification makes the game accessible and ensures that the focus is on the strategy of the move rather than just visual matching. With 240 levels that have been computer-verified to be solvable, you can be sure that every puzzle has a logical path to completion. Whether you are looking for a quick break or a longer session to organize game cards, Cartilo provides a steady, meditative experience without the pressure of a ticking clock.

How to Play This Card Sort Game Online

The mechanics of Cartilo are simple and intuitive, focusing on a tap-to-move system that allows you to rearrange cards with ease.

1. Tap on any pile to select the top card currently visible.
2. Tap on another pile where you want to move that card.
3. The card will glide to the new pile if it matches the family or if the spot is empty.
4. Continue moving cards until all five cards of a family are stacked together.
5. Once a family is complete, a gold medal will appear on the pile to mark your progress.

The Rules of Cartilo

• A card can only be placed on top of another card if they belong to the same family, meaning they share the same color and symbol.
• Any card can be moved to a completely empty pile spot.
• Each family consists of exactly five cards that must be gathered together.
• Face-down cards are hidden until the cards on top of them are moved away.
• Once a face-down card reaches the top of its pile, it automatically flips over to reveal its family.
• You win the level when every card family is correctly sorted into its own pile.

Levels and Difficulty Progression

Cartilo features 240 levels that range in difficulty from Easy to Expert. In the early stages, you may only need to manage three card families, which helps you get used to the basic movement and sorting logic. As you progress, the number of families increases up to ten, significantly expanding the complexity of the board. The piles themselves also vary in size, meaning some stacks can hold more cards than others, requiring you to plan your space carefully.

Each level comes with a move goal, which serves as a benchmark for your efficiency. While you can take as many moves as you need to solve the puzzle, trying to meet or beat the move goal adds an extra layer of challenge for experienced players. Because every level is computer-verified, you can rest assured that even the most complex Expert levels have a valid solution waiting to be discovered through logical deduction.

Special pieces and twists

• Face-down cards: These cards are hidden at the start of a level and only reveal their color and symbol once they become the top card in a pile.
• Bonus pile: A free extra pile available once per day that provides an additional empty spot to help you navigate difficult card arrangements.
• Gold medal: A visual indicator that appears on top of a pile once all five cards of a specific family have been successfully sorted.

Strategy Tips for the Card Sort Puzzle

Prioritize Face-Down Cards

In levels with hidden cards, your first goal should be to reveal them. You cannot plan your full strategy until you know which families are buried in the stacks. Focus your initial moves on clearing the piles that contain face-down cards to bring them to the top.

Keep an Empty Spot Available

An empty pile is your most valuable asset in a stack sort puzzle. Try to clear one pile completely and keep it open as a temporary transit point. This allows you to shuffle cards around without blocking other families you are trying to build.

Work from the Top Down

Look at the cards currently available on top of all piles. If you see two cards of the same family, try to combine them immediately. This reduces the number of active piles you need to monitor and slowly builds toward the five-card goal for that family.

Use the Unlimited Undo

Since there is no timer, you can experiment with different sequences of moves. If you find yourself in a position where no more moves are possible, use the undo feature to go back to a point where you had more options. It is a great way to learn the consequences of specific moves.

Manage the Move Goal

Use your first attempt at a difficult level to understand the layout of the cards. Once you know where the families are hidden, you can use the restart button to try and beat the level within the suggested move count using the knowledge you just gained.

Daily Bonus Piles

If a level with ten families feels too crowded, remember you get a free bonus pile every day. This extra slot makes it much easier to organize cards and can be the key to solving a particularly tricky Expert level when you feel stuck.

Symbol Recognition

Cartilo is designed to be color-blind friendly. Every family has a unique symbol in addition to its color. If you are playing in bright light or have trouble distinguishing colors, focus on these symbols to ensure you are matching the correct cards every time.

Who Should Play Cartilo?

Cartilo is perfect for fans of solitaire card sort puzzle mechanics who prefer a logic-based challenge. If you find satisfaction in bringing order to chaos or enjoy the process of an arrange cards game, you will likely find this experience very rewarding. It appeals to players who like to take their time, as the absence of a timer allows for deep thinking and planning. It is also an excellent choice for those who want a color-blind friendly experience, as the symbols provide a clear way to identify families without relying solely on color.
