A point-and-click game of discovery, ''Hoshi Saga'' revolves around finding stars. In each stage, you have to find a star and the fun is figuring out just what you need to do to uncover or create the star. The puzzles are many and varied, and range from the mind-numbingly easy to the hair-pullingly hard.

The ''Hoshi Saga'' series has ten installments so far:

!!This game series contains the following tropes:
* ArtShift: Stage 74 of ''Hoshi Saga 3'' has a hand-drawn scene and stars compared to the normally perfect shapes of other levels.
* BulletHell: A difficult iteration as stage 10000 [sic] in ''Dokuringo'', further compounded by your ''huge'' hitbox. After losing the first time, the game offers you a shield to make it easier. Of course, that locks you out of the 'good' ending.
* DeliberatelyMonochrome: The first three games. The next number of games are fully-colored and are much more detailed.
* EasyLevelTrick: Several stages have an inconspicuous solution to an otherwise difficult-looking puzzle.
** Stage 40 in ''Ringoame'''s esoteric solution does not involve the circles in it to reveal the star at all.
** The number of stars ranked as the difficulty can give it away, as in the stage 48, which initially appears to be a difficult {{Klotski}}, but is in fact, just a click-and-drag to the solution.
** Stage 70 in ''Ringoen'' can be difficult to align properly five times in a row, until the player realizes the background keeps track of previous attempts, so he can use those attempts to continue progress consistently.
** Even the final boss of stage 10000 has three strategies that make it a lot easier:
*** [[spoiler: Staying at the bottom middle of the screen during the first attack allows you to evade all but one of the bullets.]]
*** [[spoiler: If you move your mouse cursor out of the game border and move it back in from another side, your ship INSTANTLY teleports to the cursor. This allows you to dodge the "spinning laser" and "rings" attacks easily.]]
*** [[spoiler: Finally, right-clicking anywhere on the screen pauses the game, and left clicking anywhere else will teleport your ship to your cursor. This is VITAL for the boss' LastDitchMove.]]
* {{Fanservice}}: In each of the first three installments, there's one stage that requires you to do something almost {{ecchi}} (pulling down underwear [but not ''that'' far down], [[PantyShot blowing up women's skirts]] to reveal [[GoofyPrintUnderwear star-printed underwear]], trying to get a woman to uncover her breasts [[SceneryCensor so that they immediately get covered by stars]]...). The hints of fanservice disappear entirely after the third installment... until ''Dokuringo'', where there are no less than an entire column (five stages!) that feature nude or stripped women in full color, one requiring you to ''unzip a girl's {{Meido}} outfit'', and the winning screen you get if you clear the final stage the hard way is a drawing of a naked woman whose nipples and crotch are just barely covered by other objects. Well, the game creator ''is'' Japanese...
* GenreShift: Several final levels: ''Ringo''[==]'s final level gives off RPG tones, and ''Dokuringo''[==]'s final level is a flat out ShootEmUp.
* GroinAttack: What you need to do in one of ''3'''s stages.
* KaizoTrap: On Stage 10000, the boss's particles from after its explosion damages the player's ship.
* LastDitchMove: Stage 10000's boss uses a very nasty one when its health is depleted.
* MinigameGame
* MoodDissonance: ''Dokuringo'' only allows one stage when it's first started, which is a revamped ''Ringo'' stage 7 with a skull in place of a star. It tells you that the rest of the puzzles (unlocked after solving that one) are not simple and are not as light-hearted as the previous games' puzzles.
* MoonLogicPuzzle: Some of the stages qualify as this, giving you next to no indication of what to do in them. Especially prevalent in ''Dokuringo'', where you often have to completely ignore the obvious puzzle to search for a completely non-obvious one.
* OddlyNamedSequel: All the installments after the third one, perhaps to signify that they're in color instead of black-and-white and are [[SequelDifficultyDrop considerably easier than the first three installments]] (or ''[[SequelDifficultySpike harder]]'', for the eighth one).
* OneHitPointWonder: Stage 10000 in ''Dokuringo'' is pretty much the same as Stage 100 in ''Ringohime''... except you can only take ONE hit before losing.
* OutsideTheBoxTactic: EVERYTHING in ''Dokuringo'' requires this.
* RecurringBossTemplate: The stage 10000 boss in ''Dokuringo'' is the exact same boss in ''Ringohime'', except faster, and with a LastDitchMove. And you only take '''[[OneHitPointWonder ONE HIT]]''' to fail it instead of having infinite lives.
* RedHerring: Plenty in ''Dokuringo''; for example, the clock puzzle (stage 21 in ''Ringo'') turns out to be irrelevant to the corresponding stage 9991--not even mashing the arrow to make it fall will grant you the star. A blend of stage 60 from ''Ringoen'' and 96 from ''Ringohime'' have no relation to finding the star in stage 9997. Instead, the "'''Sta'''ge:" letters and "'''R'''eturn" button provide the clue.
* RemixedLevel: ''Dokuringo'' is almost entirely made up of stages strongly resembling that of past installments but with very different (and more difficult) solutions.
* SchizophrenicDifficulty: You can go from a 1-star puzzle that just requires you to mouse your cursor over star pieces to a 5-star puzzle that requires you to have almost superhuman reflexes.
* SequelDifficultyDrop: There's a significant drop in difficulty in the installments after the third one.
** SequelDifficultySpike: Perhaps in response to [[ItsEasySoItSucks fans' complaints about this trend]], the latest installment ''Dokuringo'' has considerably more difficult puzzles than any of the earlier installments' -- which has led fans to complain that the creator [[ItsHardSoItSucks went too far in the opposite direction]].
* ShellGame: One of the stages in ''Ringoen''. Gets a CallBack in ''Dokuringo'' where it's amped up in difficulty (instead of selecting the correct cup just once, you have to do it 3-5 times).
* ShieldedCoreBoss: Stage 10000's star, whose core is protected by four walls as well as the spinning spikes of the star itself.
* ShoutOut: The very first stage in the first game recalls the ''Mario'' series.
** Stage 100's star boss in ''Ringohime'' as well as Stage 10000's in ''Dokuringo'' are obvious references to Big Core from ''VideoGame/{{Gradius}}'', in terms of weakpoint.
* SomeDexterityRequired: Stage 30 in ''Hoshi Saga'' asks the player to type 'I will find a star' 10 times in 40 seconds to find the star. That might not come easy to some people.
* SongsInTheKeyOfLock: One stage in the second installment requires you to play "Twinkle, Twinkle Little Star" on water-filled wine glasses.
* StarShapedCoupon
* ThemeNaming:
** Ringo = [[HowDoYouLikeThemApples Apple]]
** Ringoame = Apple Candy
** Ringoen = Apple Garden
** Ringohime = Apple Princess
** Dokuringo = Poison Apple
* WaitingPuzzle:
** In the first ''Hoshi Saga'' game on stage 35, the in-game switch has to be kept on for a real-time minute before turning it off to reveal the star.
** One stage in the third installment requires you to keep your cursor still (or keep it away from the game screen) for the star to form.
