Marble Alchemy
Classic play
Aim through pegs, choose upgrades and battle five enemies. Standard rules, with no daily AI condition—learn the bounce or try a different build.
Classic play
Sweet Adventure
Collect treats, dodge obstacles, and reach the rainbow gate.
Optional AI hints
Platform Adventure
Jump across five hand-made stages, collect books, and reach school.
Optional AI hints
Sky Sprint
Switch lanes, leap roof gaps and build coin combos in a 60-second run. Read a rule for coins worth double, an extra shield or standard scoring, then see what it added.
AI challenge
Golem Stack
Drop sliding stone slabs onto a tower. Only the overlap stays, perfect drops keep the width, and a stone golem wakes at 25, 50 and 100 layers.
Local challenge
Choose between aiming, lane changes and jumps
Aim a shot and build an upgrade plan
Marble Alchemy sends each shot through pegs across five enemy fights. Classic keeps the standard rules; the daily challenge adds the condition shown before launch. Start with Classic to learn the bounce, then compare a challenge using the same aiming controls.
Read the next lane under a clock
Sky Sprint is a 60-second rooftop run. Jump low barriers and gaps; change lanes around tall crates. Use its on-screen Left, Jump and Right controls or keyboard controls. A coin chain rewards clean movement, so a safe lane can matter more than chasing the next coin.
Start with jump timing
Sweet Adventure follows a running character through treats and obstacles. Tap or press Space to jump, then jump again in the air. It is a useful choice when you want to concentrate on one action rather than steering between lanes.
Explore a stage and collect books
Platform Adventure has five hand-made stages with left, right and double-jump controls. Its optional Local Book return route needs three books before the exit opens; Candy care restores a heart for every two candies, up to three hearts. Choose a route before Start; the player still makes every move.
What AI changes in these games
In the Marble Alchemy daily challenge, AI can select a reviewed condition such as doubled first-hit damage or a life restored after an enemy win. The displayed condition locks for the run; the peg physics and your upgrades remain game rules.
Sky Sprint can use standard scoring, double coin value or a one-hit shield. AI supplies a mission and selects a reviewed rule; it does not generate the obstacle course or steer the courier.
The two platform games offer optional companion hints. Platform Adventure also offers the local study routes described above. Hints offer coaching while you keep control of movement. Check the source label to see whether a route was chosen locally or with AI.
Check the mode and source label before a run. Classic uses standard rules; free Local challenges and offline coaching stay available if the AI service cannot respond. Gameplay previews label the mode they recorded.
